Try a different network, @ngoral - for example, try using a VPN or the cellular data on your phone instead of wifi.
If that doesn’t work, and your network seems fine otherwise, you should contact Bitwarden support directly at:
I am sure they could help troubleshoot.
One more thing you can try, @ngoral - what happens if you login via the web vault at:
You can do this from any device.
Whoa. That was veird. I’m using only my cell phone and sharing network from it to my laptop, so there were no options of switching network. What worked though, is to reboot the phone (I had no other network problems except bitwarden). Now everything’s working.
(logging from web (vault.bitwarden.com) hasn’t worked by the time I was asking a question, but it’s working now, as login from every other place)
Thank you!

Sure enough, a subsequent login attempt succeeded without any changes on my end–less than an hour after I first encountered the issue.
I am experiencing the exact same problem, “unexpected error”, both in vault and add on, i’ve uninstalled add on, have reinstalled, still same problem, it is not a network error either as using a different browser logs in without any problem so it must be a browser issue, but I cannot really work out where the problem would be as i’ve not changed anything on firefox.
Thanks everyone, the team is investigating and updates will be posted on https://status.bitwarden.com/
I received the exact same email after contacting support, but I am still unable to log in for some reason.
TOTP is currently broken on the forums because the server clocks are lagging: TOTP broken on Bitwarden forums
If Bitwarden’s server clocks are out-of-sync across the board–not just on the forums–that would cause all sorts of weird issues like this.
TOTP authentication is working fine for me here on the forums and the Bitwarden vault. I don’t think that’s it.
Probably not, but it’s one of those obscure infrastructure issues that nobody ever thinks to check. A few servers with out-of-sync clocks can cause all sorts of strange issues that are difficult to track down unless someone happens to notice.
I’m getting this error with the MacOS client while it’s working fine in the Chrome extension as well as at https://vault.bitwarden.com/ 
Hey @oscar, and welcome to the forums! Are you on the latest desktop version? I haven’t bumped into that one on my mac desktop app but if you’ve double checked that you’re using the correct email + password, please send your info to the support team here.
Same problem here, also getting the server not responding issue. i am using mac with desktop client and web extension
The server not responding is probably due to the current maintenance window for the 2022.8.0 release: https://status.bitwarden.com/
same here.
cannot log in on Mac app, browser, and Safari add-on.
message reads: an unhandled server error has occurred.
and after about 20mins trying, it works now.
Stay tuned, server + web are currently undergoing scheduled maintenance and access to cached data in Bitwarden clients should still be available 2022.8.0 Scheduled Maintenance Window - Status Page - Bitwarden
