Can’t connect to SSH on private IP through VPN gateway

Morning, everyone,

I’ve been having a strange problem for a few hours. I was SSH connected on my Azure virtual machine and my SSH connection suddenly froze (without disconnecting). I closed my shell and restarted my SSH session without success. I checked the NSGs with neighboring machines I connect well to, the NSGs are almost identical. I tried to reboot the machine, redeploy the machine, reset the SSH configuration, reset the user account, without success too. I can easily connect to other machines on the same subnet. I can connect on public IP. I feel like there’s a problem between the VPN gateway and the private IP… Any ideas?

Thank you

Note : I have the following entry in the health status :
