Connect to VM on Hyper-V server
I can't connect to a VM running on top of hyper-V server 2019. It just spins at connecting. Downloading the RDP file and connect that way works fine so it seems to be an admincenter issue. ...
First of all check communication ports;
5985 HTTP and 5986 HTTPS for WinRM
2179 for VM console access (Hyper-V socket)
3389 if using RDP fallback
Also check gateway has valid certificates (self-signed certificates can sometimes cause connection hangs).
Check WAC Extension version
Go to Extensions in Admin Center - check the Hyper-V extension.
If outdated, update it. Some older builds had bugs where console connections hung indefinitely.
