Hi,

I’m trying to configure HA on my Veeam Backup Server. Has anyone seen this or ran into a similar issue?

 

I can ping both servers from IP and FQDN. Both have DNS entries. I ran through the pre-requisites of allowing HA to be configured from the Host Management, Now, I’m at a loss ..any ideas?

Yes this is an issue with the SSL certificate on the secondary node.  If you change the IP of the secondary node you will get it to work.  I had to do this and support is investigating for me.

It is actually what is stored in the DB for the SSL and the thumbprint has changed so it does not see this and there is a bug with the popup window showing to validate the new SSL thumbprint.  Hence why changing the IP works.

This was from Support back to me -

I have been able to confirm the certificate window not being presented after the certificate change is also a known issue, just took a while to find the write wording to find the page. The issue has been investigated and it does log to be slated to be corrected in a future release.

I seem to recall that both nodes must be on the same subnet. Is that the case here?

Based on the screenshot they are.

Just to be sure. It wasn't so clear to see because of the other window 😅

Yep for sure the popup window blocks the other. 😋
