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

Question

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

Answer 2

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
