Single user unable to log into webinterface - 405 not allowed

Nextcloud version: 24.0.2 / 24.0.3
Operating system and version: via Docker on Synology DSM 6.2.4
Apache or nginx version: nginx reverse Proxy on DSM + internal server in docker image
PHP version: unknown

Without known changes one single user (myself) is not able to log in into the Nextcloud webinterface any more. The admin and other users work without problems, and my Nextcloud client still syncs without problems.
The webinterface shows “Melde an…” with a turning circle. After 60 seconds I get the error “405 Not Allowed nginx”. I already upgraded from 24.0.2 to 24.0.3 but the problem still occurs.

Is this the first time you’ve seen this error? (Y/N): It happens every time I try to login

Steps to replicate it: Only possible with my account, but every time
