I recently experienced the same issue after upgrading the Bitwarden app on iOS to the latest version. The version of the vaultwarden I'm self-hosting was 1.2x, but recently I upgraded the server to the 1.32.0 version of docker image and successfully logged in from the app to my self-hosting server. Just in case, please try replacing the docker image on the self-hosting server with the latest 1.32.x image or higher. In my case, the problem was completely resolved after upgrading the version of the server.

So here's a strange thing, I have updated to the latest version, 1.32.0, and I'm still seeing the error over and over. Do you happen to know what the root cause is? Every client is fine except for iOS.

bad news @mcblum ... have U tried from safari ? its the same also from safari ? or only from bitwarden app ?

Try the testing tagged images maybe?
Or try to fully purge/remove the app including data. This also happens sometimes on Android for some reason. That the cached data causes issues because of previously working, but in a new version wrong sync data.

Deleting all info and getting fresh data from the latest (or testing) container images might solve this.

upgraded to latest docker vaultwarden and still having the same issue on ios 18.

Login does not work.

[BlackDex]

As mentioned in an other discussion, use the testing tagged containers which have a fix specifically for iOS clients. A stable release will be created soon.

tried vaultwarden/server:testing. Still getting the same error on ios18. Thanks

[BlackDex]

Any logs maybe. Just shouting it doesn't work, doesn't help.

[kcris]

I am not shouting. I had already posted the logs in another thread.

Updated again and got the Version 1.32.2-65629a99 now and it works. Thank you

For anyone hitting this login loop on the mobile app with a self-hosted server — the app authenticates, briefly shows a screen, then bounces back to the login screen, while the web vault works fine:

In our case the root cause was simply an outdated Vaultwarden. The container was pinned to vaultwarden/server:latest, but the local image had never been re-pulled, so it was stuck on 1.34.3 (~12 months old). Every server response was 200 OK — login, prelogin, /api/connect/token, and /api/sync all succeeded (the vault was even fetched) — yet the recent Bitwarden mobile app kept looping back to the login screen. Clock (NTP) and TLS were both fine.

docker compose pull && docker compose up -d to upgrade to 1.37.0 fixed it instantly. The SQLite DB auto-migrated without any issue (back up your data volume first, just in case).

Gotcha worth highlighting for others: recreating a :latest container does NOT pull a newer image — you have to docker compose pull explicitly. It's easy to silently run many months behind, which is exactly what triggered the incompatibility with the current mobile app here.
