The feature

Feature Request: Support for custom domains in app deep linking

Situation:

Immich can be self-hosted behind a reverse proxy and accessed via a custom domain (e.g. immich.domain.com).

Problem:

When clicking on a link to such a domain (e.g. in an email or messenger), Android opens it in the browser instead of launching the Immich app.
Currently, the app only recognizes predefined domains (e.g. my.immich.app), with no option for users to add their own.

Requested Feature:

Allow custom domains to be registered as supported web addresses, so that links like https://immich.domain.com open directly in the app instead of the browser.

Primarily needed on Android, but would also benefit iOS users.

There's no way to do this dynamically; the only way would be to build your own version of the app.

So there is no way for the app to pass the server URL as a supported link to Android?

I found a workaround and created an additional entry for https://my.immich.app in my dns server and reverse proxy. So i can direct my users to the app via this domain.

Would you please elaborate as to how you did that?

General approach:

1. Local DNS: Set a DNS rewrite pointing the domain to your Reverse Proxy IP.

2. Reverse Proxy: Route incoming requests for the domain to your Immich instance.

3. Custom SSL: Generate a TLS certificate for the domain using a local Root CA (e.g. mkcert).

4. Trust Root CA: Install and trust your Root CA certificate on all client devices so browsers and the Immich app accept the HTTPS connection.

Note: This setup will only work while connected to your local network (or via VPN resolving to your local DNS) and requires manually trusting the Root CA on each new device.
