V-check-user-2fa error in Hestia error.log

On one Hestia installation (v1.6.0, Ubuntu 20.04 (x86_64) apache+nginx multiphp) I noticed yesterday the following lines in /var/log/hestia/error.log:

2022-06-22 01:48:33 v-check-user-2fa  'admin' [Error 1]
2022-06-22 01:48:35 v-check-user-2fa  'admin' [Error 1]

It seems the error is logged whenever I sign in the Hestia Web UI with the admin user, who has 2FA enabled and working as expected.

Do I need to do something about it and if so what?
