Check the time on your phone.
The 2FA code on the server only changes when you change it

You have to have the correct time on your phone and it has to match the web server - the web server shows it (in tiny letters) at the bottom left in UTC on the server (the correct time) and your device time in the bottom right - which may or may not be right.

Edit: the console log shows you checking the time each time just after 30s so it would appear each time it was too slow with the previous 30s code.
The code changes every 30s at HH:MM:00 and HH:MM:30 (and you can only try it once each 30s)
