MySQL serverw as down at the time the issue happened. yes yes If this shall be a multiservers etup, then you have an ispconfig interface on the master server obnly and all servers sow up there. If you have two interfaces where you logged in and each server shows up only in its own interface, then this is not a multiserver setup, it's just two single servers which are not connected to each other.
Crap, that's what I figured. Is it possible to make this setup in it's current state into a multi-server setup?
Now that I think about the architectures, it probably makes more sense to have the 2 single servers since one is in the cloud and one is physical. Cool, I'll update the 'services' per previous post
Just as info: No, you would have had to reinstall ISPConfig (not the whole server, just ispconfig) as the connection between the systems is established by the ispconfig installer.
