Can't login with pocketId

[leolivier]

Hello,

After logging into Sync-In via the web app with my Pocket ID, I am redirected to:
https:///api/auth/oidc/callback?code=AUTH_CODE_HERE&state=...

but I get: {“statusCode”:404,‘message’:“OIDC authentication failed”}

and I have an error in my Sync-In container log that says:

[2026-04-12 17:15:21] ERROR (71): [AuthProviderOIDC] [handleCallback] OIDC callback error: HttpException: OAuth state is missing | req-28

      "response": "OIDC authentication failed",
      "status": 400,
      "name": "HttpException"
    }

The key point, it seems to me, is the first line, which says

ERROR (71): [AuthProviderOIDC] [handleCallback] OIDC callback error: HttpException: OAuth state is missing | req-28 

How can I set the OAuth state?

Any clue?

Try this configuration example : https://pocket-id.org/docs/client-examples/immich

J'ai rajouté
https:///auth/login
https:///user-settings
app.syncin:///oauth-callback

et maintenant, au login j'ai:
{"statusCode":400,"message":"OIDC authentication failed"}

et dans le log du container sync-in
err: {
"type": "HttpException",
"message": "OIDC authentication failed",
"stack":
HttpException: OIDC authentication failed
at AuthProviderOIDC.handleCallback (/app/server/authentication/providers/oidc/auth-provider-oidc.service.js:144:23)

Please read the documentation; this is not how you set up OIDC authentication.
