How to connect to Hyper-v?

Question

System administration

Hello, I ran into a problem connecting to the Hyper-v server, when I connect, an error appears that the RPC service is not running

. Everything worked before, I can’t say what has changed since that moment, but the only thing that has been significant has been changed router. The machine with which I am trying to connect to the server is in another branch, they are connected by VPN ipsec and are in the same domain, initially everything worked. I tried to disable the firewall, but there is no result. The settings in the server are made for remote control,
what can be?
