Error with credentials after reinstalling the additional scan server.

[SssSss]

I had to downgrade an additional scan server from 12.6.0.11 version to 12.5 version. I uninstall the 12.6.0.11 and install 12.5 as additional server using article "Set up a multi scanning server Lansweeper installation", copied the Key\Encryption.txt file from main server and use ConfigEditor to correct database user password. Now the additional scan server in the correct state at the main page. But any windows asset show the error "No valid credentials found. Check encryption file". And at the Service\errorlog.txt records "DEBUG No credentials were used for %COMPUTERNAME%"

What else do I have to do to get the server start using credentials?

Hi 

If you edit and re-save the credentials, they will be encrypted using the correct encryption file.
Credential encryption is handled by the web console, so if this is running on a different server, it must have the same encryption file as the scan server.
