Hi
Have you had a look at the requirements here: https://helpcenter.veeam.com/docs/one/deployment/ports.html?ver=120
Looks like your Veeam One install is not able to connect to your VMware infrastructure correctly.

Hello
The server is a hyper V server and the Windows firewall is already turned off. I dont think the port should still affect it, but will check.
Also it worth nothing that the servers were added successfully 3 days ago and all was fine up until this morning when this just suddenly came up.

No worries
On the top left corner, you have a link where it says ‘Configuration issues (3 detected)’
Have you had a look there?

I removed a server that was having the same issue and tried to add it again, it still comes up with the same error “ Uncaught exception thrown by method called Reflection ”.
Do not even know what that error is pointing to

It may be worth opening a Support Case as well if you have not yet done so.

Hi
Have you tried adding the host via hostname iinstead of IP? I saw a similar issue on the Forums.
Have you performed any Veeam upgrades?

Also, is UAC on, on this Hyper-V host? Have you recently installed Win updates? Have you tried something as simple as rebooted both the HV and VONE servers, then re-attempting to add?
Userlevel 4
Yes I rebooted both servers and it did not help
I could not try the UAC step, because I would not be allowed to restart.
The solution that worked was that I just ran the VONE ISO again and installed and it fixed the issue.
Such a simple step .
Thank you

Interesting that you had to run a reinstall again, but nice to see it working.

Makes me wonder if the Veeam ONE agent wasn’t running properly and reinstalling resolved that issue?
