Resolved Plesk does not work after upgrade from 17.8.11 to 18.0.20

[Sergio Neuro]

Plesk stopped working after upgrading to 18.0.20. It just shows a plain link on white screen labeled "web admin edition" which points to "https://mydomain.com:8443/smb/web/view" and infinitely loops within URL "https://mydomain.com:8443/login_up.php?success_redirect_url=https://mydomain.com:8443/smb/web/view". Tested that in all major browsers.

Now I'm unable to manage my webhosting.

@Sergio Neuro please contact our support for faster resolution Plesk Help Center

Also, provide the information from autoinstaller.log

Please try in incognito window as well.
If doesn't help we are needed in more details and most probably access to the server will be required. So as Anton already said please contact Plesk Help Center.

Does not work in incognito.

Unfortunately I cannot provide access to the server, but I can provide more details from ssh.

Also, is it possible to roll back to Plesk 17 until the newer version becomes more stable?

Could you tell us your IP address at least (maybe via private message).
Please also provide the output of console command: plesk version

@Sergio Neuro you have access to your server via ssh but your plesk user interface is not working. There could be something happened while installation. Have you tried reaching server by using your ip address like https://server-ip-address:8443?

Server reboot solved the issue. Thanks to @SibProgrammer for the advice.
