Reproduction steps

Just opening the app results in the remote sync process not working.

Additional information

I've also seen the following error in the immich_server docker container, I don't know if it might be relevant:

[Nest] 23  - 10/16/2025, 9:57:15 AM   ERROR [Api:ErrorInterceptor~dgu457an] Unknown error: Error [ERR_HTTP_HEADERS_SENT]: Cannot set headers after they are sent to the client

[masterwishx]

Have same issue, converted to discussion #22960

[bo0tzz]

@UnaDeKalamares is there anything else in the server logs?

immich/server/src/controllers/sync.controller.ts

Lines 47 to 52 in 9d63960

	try {
	await this.service.stream(auth, res, dto);
	} catch (error: Error | any) {
	res.setHeader('Content-Type', 'application/json');
	this.errorService.handleError(res, error);
	}

This setHeader might be invalid and swallowing the actual error? Error [ERR_HTTP_HEADERS_SENT]: Cannot set headers after they are sent to the client.

[salacr]

I have the same/simmilar issue, some of the photos / videos aren't synced :/

[alextran1502]

Please try connecting to your instasnce over local IP, if it works and doesn't work via the reverse proxy then the issue is from the proxy setup

[salacr]

Do we know what specific settings should be done on the proxy server? (WebSockets / big headers.. I don't know)
My setup is a little bit tricky (NGINX -> Traefik -> Immich), but I don't see any specific error, and other apps work without issues

@bo0tzz I've also seen the following trace. Other than that, I'm afraid nothing else shows up:

@alextran1502 I've tried setting the IP manually, but I'm afraid I'm seeing the same exception (in my case, I've got whatever default proxy OMV might set by default):

Regardless of that auth exception, I can login and browse my files via the Immich app. It's the Android app's timeline which isn't loading up, apparently.

@UnaDeKalamares With the logs from the server, it makes sense now. It looks like your database is corrupted somehow. Has there been a recent power loss to the server? Is your DB_DATA_LOCATION a network mount?

[UnaDeKalamares]

I haven't experienced any power loss recently, as far as I remember (it's connected to a UPS). The DB_DATA_LOCATION is in a local drive connected to the server via SATA.

Is there anything I can do to try and restore the DB? I haven't created any album, nor used the face recognition features, so I suppose there isn't really any important data?

[UnaDeKalamares]

So, it is my understanding that my only solution would be to destroy and create back all the resources?

[UnaDeKalamares]

I tried destroying the DB, and it seemed to solve the issue. However, now I see a bunch of error loading images; it doesn't seem to generate their thumbnails. Now I cannot find the logs, but It looked like Immich was unable to find some files (needles to say, said files exist). I'm on 2.2.0 now.

I have the same error message on my OnePlus 13. Sync/Backup was not enabled previously and i only enabled it after migrating to 2.0.1 (i am now on 2.1.0). It works when connecting locally to immich-server and fails when connecting through any proxy.

Not sure how related to proxy.
