I also have a problem since the update,
I have a black screen and it is no longer possible to connect to the server, my provider says that at his place everything is normal (he uses the ip address)
I have a second subscription and no problem with this one (it uses the mac address).
When I can no longer connect, the server loading hangs on 10%, the next day everything is back to normal and it works for one or two days.
I tested with a static ip address, it doesn't change anything, I put the FORMULER Z8 in a DMZ of my router, it doesn't change anything.
when i was in beta everything worked fine.
hoping that the support finds the solution.
