Temporary error on initial login try

I have latest NC installed with snap on Ubuntu 24.04.
Everything works fine, but this little detail gets on my nerves.
Sometimes when I try to login with saved credentials I’m getting “Temporary error”. Immediately after that when I push “Log In”, I am able to login.
Does anybody know how to solve this? Is it browser related?

run the Nextcloud snap debugging script and post the output here

the log is “Tried to log in but could not verify token”, it looks like it happens only on Chrome, clearing chrome cache didn’t help. Here is the log:
{“reqId”:“dEvwcIBUORyoAEoIMbzm”,“level”:1,“time”:“2025-02-24T14:20:39+00:00”,“remoteAddr”:“192.168.1.6”,“user”:“–”,“app”:“core”,“method”:“POST”,“url”:“/index.php/login”,“message”:“Tried to log in but could not verify token”,“userAgent”:“Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/132.0.0.0 Safari/537.36”,“version”:“30.0.5.1”,“data”:{“app”:“core”,“user”:“username”},“id”:“67beca117ba74”}

I also encountered “Temporary error”. Just want to report, this happened with recent Firefox versions as well.
