CloudC2 - 2FA and authentication issues

[pr0t31n]

I ran into a problem when I checked the box to force 2FA on my account. It brought up the 2FA TOTP QR and I used Google Authenticator to add it. BUT... the code was not accepted. Attempted multiple times with multiple authenticators and re-generated the QR (different TOTP each time). It consistently told me incorrect OTP. 

So. I performed an account recovery against the server by following the procedure exactly. It says that it worked, but all attempts to login are now greeted with the "Your credentials are not valid." error. 

I have attempted recovery multiple times with the same result. I am at a loss here. I would like to regain access to my account with my devices still connected.

I guess you need to be more specific about your C2 setup to be able to try to find something that would affect it all. I experience no issues using Google Authenticator based 2FA along with C2.

I just reinstalled version 3.4.0 fresh, I can't set up 2FA as well with QR-code scanning method- the code is not accepted. I also checked my server time- it was in incorrect timezone, I fixed it, even rebooted the whole server, but still can't setup 2FA to my account- `Error: Invalid code; Ensure server and device time are set properly.` 

I remember I had exactly the same issue in spring or sth as well when I last rebuilt my server from scratch. I think I got my 2FA working by using the code-string manually, which is more tedious.
