Running QB Enterprise 2018 on Server 2012.

I cannot switch over to multi-user mode from the workstation and I am getting Error H202.

I have tried the relevant help articles.  On the QB DB Server manager it says all is running fine, but on the QB Desktop File Doctor it says "QBDBMgrN not running on this computer."

I have also tried the relevant help article for that one as well.  Anyone go through this recently?
