Password or 2FA incorrect after firmware update from 1.5 to 1.7.2 to

Password or 2FA code is not correct!

Updated comet from 1.5 to latest stable 1.7.2.

Most of these issues are related to the inability to synchronize time. If you disable KVM internet access, it's best to also turn off 2FA, as 2FA cannot be used without a internet connection.

I disabled internet access because I only want to use it local.

2FA worked until the firmware update WITHOUT internet access.

Normally 2FA shouldn’t be affected by time. I will try to enable it shortly for time sync and then disable it again.

Enabled internet, now it works.
