Hello everyone, I'm experiencing an issue. If I enable two-factor authentication, when I try to log in to ISPConfig, it gives me the error: failing sending an email to [email protected]. Would someone be so kind as to suggest how I can solve this error? cat htf_report.txt ##### SERVER ##### IP-address (as per hostname): ***.***.***.*** [WARN] could not determine server's ip address by ifconfig [INFO] OS version is Debian GNU/Linux 11 (bullseye) [INFO] uptime: 16:09:31 up 18:41, 1 user, load average: 0.00, 0.00, 0.00 [INFO] memory: total used free shared buff/cache available Mem: 3.7Gi 2.0Gi 739Mi 110Mi 1.0Gi 1.4Gi Swap: 0B 0B 0B [INFO] systemd failed services status: UNIT LOAD ACTIVE SUB DESCRIPTION 0 loaded units listed.

Try sending e-mail to that address, what happens? See mail.log for info on what happens with that e-mail. Is this a system that was just now installed? The common issues report looks like nothing is working. Next time, post it in CODE tags.
If I send an email to that address, it works. The problem occurred when, due to an issue with receiving emails, I accessed the database and manually set the opt_type to ISPConfig access without two-factor authentication. Having solved the email issue (although there's still one, but they do arrive), I reset the two-factor authentication.
