Same error here, but on a snap installation, i have been having this issue for the last 2 weeks or so, but very randomly

I got the same problem, but mainly when logging in via the iOS App.
Also on a freshly setup device, so no cache or anything could be the issue here.

Any development on this issue?

there is another thread [Bug]: Temporary error Please try again During Login · Issue #43301 · nextcloud/server · GitHub that describes the same issue.
First thought it is an CSRF related problem but thats not the case.

Have you tried completely clearing the cookies and cache of your web browser?
whenever we do an update of our nextcloud (major or minor update) a lot of users have problems (e.g. incomplete pages) that are solved by deleting the browser cache.
If you can successfully connect through the mobile app or desktop synchronization client when there is an issue on the web, this is likely the problem…

Check out this topic → Browser Cache must be deleted after update - :construction: Installation - Nextcloud community

hey! i cleared all my cookies and i can now login.

unfortunately this does not solve the problem.
