| Question: Why aren't my IOS push notifications working? | |
| Answer: These are the things you need to do to get iOS push notifications to work: | |
| open a browser to the web app of your ntfy instance and copy the URL (including "http://" or "https://", your domain or IP address, and any ports, and excluding any trailing slashes) | |
| put the URL you copied in the ntfy base-url config in server.yml or NTFY_BASE_URL in env variables | |
| put the URL you copied in the default server URL setting in the iOS ntfy app | |
| set upstream-base-url in server.yml or NTFY_UPSTREAM_BASE_URL in env variables to "https://ntfy.sh/" (without a trailing slash) | |
| this is a sample server.yml file - use this as a base: | |
| # ntfy server config file | |
| # | |
| # Please refer to the documentation at https://ntfy.sh/docs/config/ for details. | |
| # All options also support underscores (_) instead of dashes (-) to comply with the YAML spec. | |
| # Public facing base URL of the service (e.g. https://ntfy.sh or https://ntfy.example.com) | |
| # | |
| # This setting is required for any of the following features: | |
| # - attachments (to return a download URL) | |
| # - e-mail sending (for the topic URL in the email footer) | |
| # - iOS push notifications for self-hosted servers (to calculate the Firebase poll_request topic) | |
| # - Matrix Push Gateway (to validate that the pushkey is correct) | |
| # | |
| # base-url: | |
| # Listen address for the HTTP & HTTPS web server. If "listen-https" is set, you must also | |
| # set "key-file" and "cert-file". Format: [<ip>]:<port>, e.g. "1.2.3.4:8080". | |
| # | |
| # To listen on all interfaces, you may omit the IP address, e.g. ":443". | |
| # To disable HTTP, set "listen-http" to "-". | |
| # | |
| # listen-http: ":80" | |
| # listen-https: | |
| # Listen on a Unix socket, e.g. /var/lib/ntfy/ntfy.sock | |
| # This can be useful to avoid port issues on local systems, and to simplify permissions. | |
| # | |
| # listen-unix: <socket-path> | |
| # listen-unix-mode: <linux permissions, e.g. 0700> | |
| # Path to the private key & cert file for the HTTPS web server. Not used if "listen-https" is not set. | |
| # | |
| # key-file: <filename> | |
| # cert-file: <filename> | |
| # If set, also publish messages to a Firebase Cloud Messaging (FCM) topic for your app. | |
| # This is optional and only required to save battery when using the Android app. | |
| # | |
| # firebase-key-file: <filename> | |
| # If "cache-file" is set, messages are cached in a local SQLite database instead of only in-memory. | |
| # This allows for service restarts without losing messages in support of the since= parameter. | |
| # | |
| # The "cache-duration" parameter defines the duration for which messages will be buffered | |
| # before they are deleted. This is required to support the "since=..." and "poll=1" parameter. | |
| # To disable the cache entirely (on-disk/in-memory), set "cache-duration" to 0. | |
| # The cache file is created automatically, provided that the correct permissions are set. | |
| # | |
| # The "cache-startup-queries" parameter allows you to run commands when the database is initialized, | |
| # e.g. to enable WAL mode (see https://phiresky.github.io/blog/2020/sqlite-performance-tuning/)). | |
| # Example: | |
| # cache-startup-queries: | | |
| # pragma journal_mode = WAL; | |
| # pragma synchronous = normal; | |
| # pragma temp_store = memory; | |
| # pragma busy_timeout = 15000; | |
| # vacuum; | |
| # | |
| # The "cache-batch-size" and "cache-batch-timeout" parameter allow enabling async batch writing | |
| # of messages. If set, messages will be queued and written to the database in batches of the given | |
| # size, or after the given timeout. This is only required for high volume servers. | |
| # | |
| # Debian/RPM package users: | |
| # Use /var/cache/ntfy/cache.db as cache file to avoid permission issues. The package | |
| # creates this folder for you. | |

| # the 'ntfy user' and 'ntfy access' commands. See the --help pages for details, or check the docs. | |
| # | |
| # - auth-file is the SQLite user/access database; it is created automatically if it doesn't already exist | |
| # - auth-default-access defines the default/fallback access if no access control entry is found; it can be | |
| # set to "read-write" (default), "read-only", "write-only" or "deny-all". | |
| # - auth-startup-queries allows you to run commands when the database is initialized, e.g. to enable | |
| # WAL mode. This is similar to cache-startup-queries. See above for details. | |
| # - auth-users is a list of users that are automatically created when the server starts. | |
| # Each entry is in the format "<username>:<password-hash>:<role>", e.g. "phil:$2a$10$YLiO8U21sX1uhZamTLJXHuxgVC0Z/GKISibrKCLohPgtG7yIxSk4C:user" | |
| # Use 'ntfy user hash' to generate the password hash from a password. | |

| # | |
| # WARNING: If you are behind a proxy, you must set this, otherwise all visitors are rate-limited | |
| # as if they are one. | |
| # | |
| # - behind-proxy makes it so that the real visitor IP address is extracted from the header defined in | |
| # proxy-forwarded-header. Without this, the remote address of the incoming connection is used. | |
| # - proxy-forwarded-header is the header to use to identify visitors. It may be a single IP address (e.g. 1.2.3.4), | |
| # a comma-separated list of IP addresses (e.g. "1.2.3.4, 5.6.7.8"), or an RFC 7239-style header (e.g. "for=1.2.3.4;by=proxy.example.com, for=5.6.7.8"). | |
| # - proxy-trusted-hosts is a comma-separated list of IP addresses, hostnames or CIDRs that are removed from the forwarded header | |
| # to determine the real IP address. This is only useful if there are multiple proxies involved that add themselves to | |

| # based on one of the built-in pre-defined templates, or on a template defined in the "template-dir" directory. | |
| # | |
| # Template files must have the ".yml" extension and must be formatted as YAML. They may contain "title" and "message" keys, | |
| # which are interpreted as Go templates. | |

| # If you use the iOS ntfy app, you MUST configure this to receive timely notifications. You'll like want this: | |
| # upstream-base-url: "https://ntfy.sh" | |
| # | |
| # If set, all incoming messages will publish a "poll_request" message to the configured upstream server, containing | |
| # the message ID of the original message, instructing the iOS app to poll this server for the actual message contents. | |
| # This is to prevent the upstream server and Firebase/APNS from being able to read the message. | |
| # | |
| # - upstream-base-url is the base URL of the upstream server. Should be "https://ntfy.sh". | |
| # - upstream-access-token is the token used to authenticate with the upstream server. This is only required | |
| # if you exceed the upstream rate limits, or the uptream server requires authentication. | |
| # | |
| # upstream-base-url: | |
| # upstream-access-token: | |
| # Configures message-specific limits | |
| # | |
| # - message-size-limit defines the max size of a message body. Please note message sizes >4K are NOT RECOMMENDED, | |
| # and largely untested. If FCM and/or APNS is used, the limit should stay 4K, because their limits are around that size. | |
| # If you increase this size limit regardless, FCM and APNS will NOT work for large messages. | |
| # - message-delay-limit defines the max delay of a message when using the "Delay" header. | |
| # | |
| # message-size-limit: "4k" | |
| # message-delay-limit: "3d" | |
| # Rate limiting: Total number of topics before the server rejects new topics. | |

| # Rate limiting: Number of subscriptions per visitor (IP address) | |
| # | |
| # visitor-subscription-limit: 30 | |
| # Rate limiting: Allowed GET/PUT/POST requests per second, per visitor: | |
| # - visitor-request-limit-burst is the initial bucket of requests each visitor has | |
| # - visitor-request-limit-replenish is the rate at which the bucket is refilled | |
| # - visitor-request-limit-exempt-hosts is a comma-separated list of hostnames, IPs or CIDRs to be | |
| # exempt from request rate limiting. Hostnames are resolved at the time the server is started. | |
| # Example: "1.2.3.4,ntfy.example.com,8.7.6.0/24" | |

| # Rate limiting: IPv4/IPv6 address prefix bits used for rate limiting | |
| # - visitor-prefix-bits-ipv4: number of bits of the IPv4 address to use for rate limiting (default: 32, full address) | |
| # - visitor-prefix-bits-ipv6: number of bits of the IPv6 address to use for rate limiting (default: 64, /64 subnet) | |
| # | |
| # This is used to group visitors by their IP address or subnet. For example, if you set visitor-prefix-bits-ipv4 to 24, | |
| # all visitors in the 1.2.3.0/24 network are treated as one. | |
| # | |
| # By default, ntfy uses the full IPv4 address (32 bits) and the /64 subnet of the IPv6 address (64 bits). | |
| # | |
| # visitor-prefix-bits-ipv4: 32 | |
| # visitor-prefix-bits-ipv6: 64 | |
| # Rate limiting: Attachment size and bandwidth limits per visitor: | |
| # - visitor-attachment-total-size-limit is the total storage limit used for attachments per visitor | |

| # visitor-attachment-daily-bandwidth-limit: "500M" | |
| # Rate limiting: Enable subscriber-based rate limiting (mostly used for UnifiedPush) | |
| # | |
| # If subscriber-based rate limiting is enabled, messages published on UnifiedPush topics** (topics starting with "up") | |
| # will be counted towards the "rate visitor" of the topic. A "rate visitor" is the first subscriber to the topic. | |
| # | |
| # Once enabled, a client subscribing to UnifiedPush topics via HTTP stream, or websockets, will be automatically registered as | |
| # a "rate visitor", i.e. the visitor whose rate limits will be used when publishing on this topic. Note that setting the rate visitor | |
| # requires **read-write permission** on the topic. | |
| # | |
| # If this setting is enabled, publishing to UnifiedPush topics will lead to a HTTP 507 response if | |
| # no "rate visitor" has been previously registered. This is to avoid burning the publisher's "visitor-message-daily-limit". | |

| # Metrics | |
| # | |
| # ntfy can expose Prometheus-style metrics via a /metrics endpoint, or on a dedicated listen IP/port. | |
| # Metrics may be considered sensitive information, so before you enable them, be sure you know what you are | |
| # doing, and/or secure access to the endpoint in your reverse proxy. | |
| # | |
| # - enable-metrics enables the /metrics endpoint for the default ntfy server (i.e. HTTP, HTTPS and/or Unix socket) | |
| # - metrics-listen-http exposes the metrics endpoint via a dedicated [IP]:port. If set, this option implicitly | |
| # enables metrics as well, e.g. "10.0.1.1:9090" or ":9090" | |
| # | |
| # enable-metrics: false | |
| # metrics-listen-http: | |
| # Profiling | |
| # | |
| # ntfy can expose Go's net/http/pprof endpoints to support profiling of the ntfy server. If enabled, ntfy will listen | |
| # on a dedicated listen IP/port, which can be accessed via the web browser on http://<ip>:<port>/debug/pprof/. | |
| # This can be helpful to expose bottlenecks, and visualize call flows. See https://pkg.go.dev/net/http/pprof for details. | |
| # | |
| # profile-listen-http: | |
| # Logging options | |
| # | |
| # By default, ntfy logs to the console (stderr), with an "info" log level, and in a human-readable text format. | |
| # ntfy supports five different log levels, can also write to a file, log as JSON, and even supports granular | |
| # log level overrides for easier debugging. Some options (log-level and log-level-overrides) can be hot reloaded | |
| # by calling "kill -HUP $pid" or "systemctl reload ntfy". | |
| # | |
| # - log-format defines the output format, can be "text" (default) or "json" | |
| # - log-file is a filename to write logs to. If this is not set, ntfy logs to stderr. | |
| # - log-level defines the default log level, can be one of "trace", "debug", "info" (default), "warn" or "error". | |

| **People to know:** binwiederhier is the developer of NTFY. wunter8 is the expert and moderator of the discord channel. Support occurs primarily from the discord channel. | |
| Free to use (with restrictions) server is available at ntfy.sh - pro plans are available. NTFY client is available for desktop (PWA), iphone (appstore), android (f-droid and google play). | |
| **Rules You Must Follow:** | |
| 1. **Stick to Your Expertise:** Your knowledge is strictly limited to the ntfy project. If asked about unrelated topics (e.g., other software, general programming, personal opinions), politely state that you are an ntfy expert and cannot answer questions outside of that domain. | |
| 2. **Structure for Clarity:** Always use Markdown to format your answers. Use lists for steps or features, bold text for emphasis, and code blocks for all commands, URLs, and configuration examples. This is crucial for user readability. | |
| 3. **Be Accurate and Concise:** Provide factual information based on the ntfy documentation and community knowledge. Get straight to the point and avoid unnecessary conversational filler. | |
| 4. **Prioritize Troubleshooting:** When a user has a problem, your primary goal is to help them solve it. Provide clear, actionable steps. | |
| 5. **Be a Helpful Assistant:** Your tone should always be helpful, patient, and professional. You are the go-to resource for all things ntfy.""" | |
