I am trying to get a Red Hat cluster added to my virtual infrastructure. After inputting all the information including the credentials I click apply. After 30 seconds I get a popup stating: “A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.” 

I checked that the logs and couldn't find anything that stood out except the previously written statement. I am running RHEL 9 and port 22 is open since I am able to SSH into the server from my Backup & Replication 12 host on MS Server 2022. Has anyone run into this issue or can recommend a course of action. I have input my credentials with the IP and without (Ex. first.last@192.168.1.1).

Never used this before but maybe the help would be of assistance - https://helpcenter.veeam.com/docs/vbrhv/userguide/connecting_manager.html?ver=6

Hi ​@kghii -

So, you’re attempting to add oVirt KVM Manager to Veeam then? Are you adding a Host, or KVM Manager? Did you follow the User Guide steps?

https://helpcenter.veeam.com/docs/vbrhv/userguide/add_rhv_credentials.html?ver=6

According to the above, when connecting to KVM Manager, you must use the format:
<username>@<local user domain>

Please share a bit more info if you’re able.

Also, a Community Member and Veeam Legend created a post about this process about a yr ago...maybe worth a glance at:

Best.

    Veeam connects to the RHV/oVirt Manager API via HTTPS, not SSH. A timeout usually means:

    Port 443 is blocked by a firewall.

    The ovirt-engine service is not running.

    You’re pointing to the wrong host.

    Test from your Veeam server:

    Test-NetConnection <FQDN-or-IP> -Port 443

    If there’s no response, check firewall rules or service status on the Manager.

    best regards .-
