Immich fails to adapt when server address changes behind a redirect domain

I have searched the existing issues, both open and closed, to make sure this is not a duplicate report. • Yes The bug Hi, thanks for the great project! Problem When accessing the server through a redirect domain (e.g. .well-known/immich returns a different hostname/port), Immich resolves and caches the real address at login. All subsequent requests go directly to the cached address, bypassing the original domain. Once the real address changes (e.g. dynamic port from NAT traversal), the cache becomes stale, the app cannot connect, and backups repeatedly fail until it crashes. My attempt I tried using Automatic Endpoint Switching in the app settings, adding the redirect domain as an external endpoint so the app would re-resolve on each resume and pick up the new address. But the validation always fails (red exclamation mark) and the configuration cannot be saved. The reason: validation first resolves the real address via .well-known/immich, then sends GET /users/me to that…
