Error with OAuth and mobile application

Previously, the mobile app was working fine, but I logged out as suggested to resolve the timeline thing. Now, I cannot log back in. The app logs:
Error getting OAuth server Url: ApiException 401: <a href="https://authelia.mydomain.me/?rd=https%3A%2F%2Fimmich.mydowmain.me%2Foauth%2Fauthorize&amp;rm=POST">401 Unauthorized</a>

Authelia logs:
time="2025-09-22T12:46:04-07:00" level=info msg="Access to https://immich.mydomain.me/.well-known/immich (method GET) is not authorized to user <anonymous>, responding with status code 401 with location redirect to https://authelia.mydomain.me/?rd=https%3A%2F%2Fimmich.mydomain.me%2F.well-known%2Fimmich&rm=GET" method=GET path=/api/authz/forward-auth remote_ip=192.168.1.126

So it appears the application is trying to access https://immich.mydomain.me/.well-known/immich, which it isn't allowed to. I don't see that listed on the OAuth page. As mentioned, this used to work fine and still works fine from the Web interface. The mobile application redirect is setup and unchanged. Any ideas?

To be clear, do you have oauth set up in Immich or are you doing proxy auth?
stumpylog
stumpylogOP2w ago
oauth is setup in Immich It works fine in the Web UI and did at least once in the app
Daniel
Daniel2w ago
Oh btw you still have your domain in the first code block for the authelia URL. If you care you should edit that message :)
path=/api/authz/forward-auth
This very much sounds like proxy auth to me, i.e., some auth layer fronting Immich
stumpylog
stumpylogOP2w ago
I believe that is simply the proxy redirecting to Authelia for login, because the user isn't known In general, nothing is accessible to unknown users and they are redirected to Authelia for login. So it seems the app is trying access https://immich.mydomain.me/.well-known/immich, but isn't known yet

is not authorized to user <anonymous>, responding with status code 401
This sounds like you're not getting authed properly?
Daniel
Daniel2w ago
Yeah that's proxy auth We don't support that

The confusing thing is you say it “isn’t allowed to” access that path - if you use our built in OIDC you can indeed hit that path
stumpylog
stumpylogOP2w ago
Immich is using OIDC to login via the web. And the app was working

If you open immich in an incognito web browser, what is the first thing you see?
stumpylog
stumpylogOP2w ago
It will redirect me to authelia for login
Daniel
Daniel2w ago
Even if you go to immich.mydomain.me/.well-known/immich?
stumpylog
stumpylogOP2w ago
That's not exempted from my access control list, so yes, that needs login
Daniel
Daniel2w ago
So that is not Immich's native oauth implementation then You're fronting Immich with extra auth
stumpylog
stumpylogOP2w ago
So immich needs to be a policy: "bypass"?
Daniel
Daniel2w ago
I don't know authelia details, but the mobile app does not support proxy auth. All (api) endpoints need to be accessible directly
stumpylog
stumpylogOP2w ago
Hm, I'm not sure why it would have worked once But the workaround is pretty simple, add a bypass for the resource "^/.well-known/" and everything seems good again

To my knowledge only bypassing that is not sufficient. It's possible some functionality is still limited with that, but I am not 100% Me neither tbh 😅
stumpylog
stumpylogOP2w ago
It seems I had previously exempted /api as well, so it seems I encountered something related before
Daniel
Daniel2w ago
Yeah that makes sense to me then. Exempting those two should cover all grounds
bo0tzz
bo0tzz2w ago
Do note that if you exempt /api you might as well drop the forward auth entirely

The well know things is just for API discovery. The web is bundled into the API so there's no need for discovery there. I think alternatively you could manually add the trailing /api to the server url in the mobile app.
Daniel
Daniel2w ago
Right but that is also just like static, public content, so why bother?
