Failed to start 3CXPhoneSystem01.service: Unit 3CXPhoneSystem01.service not found.

I received an email from our lightsail hosted system which read:
A backup of your PBX at myname.3cx.us has been successfully completed. No further action is required.
Backup name: rescueBackupUpgrade.zip
Backup Path: /var/lib/3cxpbx/Instance1/Data/Backups/rescueBackupUpgrade.zip

I am unable to start nor stop any of the 3CX services.

systemctl status does not show 3CX started or stopped.

I have no console access I get a server error message when trying to log in the management console. My users get a 502 - OK when trying to log on the web client. What is the solution?

Did someone try to upgrade it to v20? No upgrade log email?

We did not. and the enduser indicated that they did not also. None of the 3CX services appears to be on the system. I cannot stop nor start them.
