Proxy headers/networking switching not working

I'm unsure of when exactly the connection stopped working but I noticed it after updating my iPhone to iOS 26. Now when I'm off my home network Immich fails to connect to my server through my external endpoint which is a proxied address and leverages proxy headers to bypass manual auth needs. Now it just fails.

I'm running the latest version of both Immich Server and Mobile app 1.142.1. On my iPhone I can still access the web UI no problem when external just the app is failing.

[Issue] [META] Experimental network features (immich-app/immich#15230)

Is it the networking switching that is experimental? or the proxy header support?

The reason I ask is even if I only use my proxied address as the server address and disable the networking switching it still fails to connect with my proxy headers. I did check my proxy as well and I'm not seeing any failed attempts.

Proxy headers are experimental

crzyitalianoOP•9/17/25, 10:30 PM

Ah got it. Well I figured it out on my end. I enabled debug logging on my proxy for fun and found the issue. The expected proxy header name changed on my proxy side and Immich was using the old ones I had configured before. After updating the headers the tokens worked again and the app can talk to Immich over external network again. Sorry to bother you all!
