Thanks for using Fusion 7. Did you try disconnect and connect the server? I ever hit this issue when I try to open a vm after my Mac sleep with server connected, then a disconnect and reconnect the server solved my issue. If it doesn't help, could you provide the support bundle after you reproduce the issue. Help-> Collect Support Information.
I have the same issue. Why do I have to reconnect manually to the server after waking up my Mac from sleep? It is really annoying. Could you save the state so that Fusion will reconnect automatically, please?
