Hi there. The same thing happened to me each time I changed server for my games website and each time it was a slightly different problem. I have changed the server 4 times during the last 10 years due to requiring better specs.
I am sure I can resolve this for you, with access to your cpanel (preferably) if you have one, or through the Terminal. I could probably also do it the same day as awarded, certainly it would be next day if we happened to have a delay in comms back and forth.
