Android APP can't connect to self-hosted bitwarden (web access no issue)

Hi i’m using Bitwarden android APP 2023.12.0 and a self-hosted bitwarden on a Syno within a docker.
This was working fine untill i changed phones. Web access on the same URL is working fine same as chrome plugin.
Also on the old phone the APP stopped working after i logged out.
After entering the correct URL and email address i get the following message: “We were unable to process your request. Please try again or contact us.” If i enter my password the following message appears: “An error has occurred. Username or password is incorrect. Try again”. I use the same username and password for web login and that works fine.
Reinstalled the app tried everything mentioned in this threat:

Nothing seems to work.

I just tried it on an Iphone and i get the same issue.

I found the issue. I needed to update the vaultwarden docker to the newest version.
This is the video on how to do this: YouTube update vaultwarden docker on synology
