Hello,
The error cipher invalid usually means that your SolidCP Server password or connection is not correct.
Please check Configuration --> Servers --> click on the "settings" button.
It should not give any connection error.
If it does please verify the url is correct and reachable from the enterprise server aswell as the password, Incase your not sure about the Server password you can reset it using the installer --> click on SolidCP Server --> settings .
At the end it will ask to reset password.
Regards,
Marco
