Hyper-V failed to enable replication for virtual machine: The server returned an invalid or unrecognized response (0x00002F78)

Hello, I recently implemented hyper-v replica in my environment, communication is between two clusters, obviously a broker was configured for each side and everything was working normally until the firmware, drivers and windows updates started, sending the replica so It works from side B to A and not from A to B. I've already redid all the settings, checked the firewall and this generic error occurs, which I can't find on any forum. I'm using port 443 and the certificates are ok, everything is registered in DNS. What could it be? I've tried everything

Hello,

Thank you for posting in Q&A forum.

If you want to firewall the replication traffic for the primary and secondary servers, open PowerShell as an administrator and enter the following command:

get-clusternode | ForEach-Object {Invoke-command -computername $.name -scriptblock {Enable-Netfirewallrule -displayname "Hyper-V Replica HTTP Listener (TCP-In)"}}

get-clusternode | ForEach-Object {Invoke-command -computername $.name -scriptblock {Enable-Netfirewallrule -displayname "Hyper-V Replica HTTPS Listener (TCP-In)"}}

If the problem is still not resolved, I recommend checking the event log to see if there is any related error information.

I hope the information above is helpful.

Best regards
