Description of Issue

Last week there were “compatibility issues” with the server update when updating. Since nothing worked, I went back to 1.8. To do this, however, I had to uninstall the server, including data.

After connecting I can either log in or start a trial. When trying to log in, I get the message that I’m already logged in.

So the only option available is restoring from a backup. After the restoration, a relaunch had to be made.

And the system was reset to zero because obviously no connection to the server could be established.

After several unsuccessful attempts, I returned to version 2, which suddenly installed without any problems (without any compatibility problems).

A database update was required for the new version, which was also carried out. But after that it was exactly the same situation: Restore from a Backup. Afterwards the relaunch and everything is back to zero because no connection to the server could be established.

Any idea how do I get out of this loop?
