Hyper-v 2019 replication error (event id 32000 Hyper-V-VMMS)

Question

Hello,

I explained my problem on a French site but I didn't get an answer :
55381dd4-4bdf-4627-8b1d-50bfc82c7aba
I was told to come and detail the problem here.

I will try to translate here but sorry if the explanation is bad.

We had host servers in WS2012-r2 on which we had hyper-v replications.

The hyper-v replication configuration was in Kerberos (port 8080). Everything has always worked well.

We switched to host servers in WS2019 (standard graphical WS2019 environment and also in core), VM migrations between servers work correctly but not replications. We have the following error message:

• Host servers belong to a corporate domain and are easily accessible on the network
• Hyper-v is correctly configured (Kerberos port 8080) on the 2 servers (main and replication)

• AD delegation rights correctly positioned on the main host server and the replication host server (Authorized service type "cifs" and "Hyper-V replica Service)

• The firewall is disabled (when enabled, Hyper-V rules are allowed for Hyper-V replica HTTP listener ports (Tcp-In)
• There is no antivirus installed
• A telnet test on the server port 8080 does not reveal any errors
• In the main server's event viewer, we have the error below
• In the event viewer of the replication server, there is no particular error

I take a lot of search on the net but have no resolution.

Thank you for your help!

We have finally found the explanation for the problem.

A proxy had been activated (by the command "netsh winhttp set proxy xx.xx.xx.xx")

It was necessary to desable it with the command "netsh winhttp reset proxy"
