Hi,
I’m having an issue opening VM consoles in the vCenter client. I’m getting the error “Unable to connect to the MKS: Failed to connect to the server xxxxxxxxx:903."
I’ll give you some info on our setup.
We have 3 clusters which are based at 2 sites.
Site A is the site I’m based at and Site B is the remote site.
Site B is where our VC server is located. There are 8 hosts based at site B.
I experience the issue on random hosts on our remote site (B). A reboot resolves the issue for a time but then it occurs again. It normally only affects one host at any one time.
All the firewall settings are identical on all the hosts.
If I logon directly to our VC server which is based at the remote site and try to open a console on the same VM the problem does not occur.
I have done some reading up and many possible causes point to firewall issues. Because this is happening on random hosts and is fixed with a reboot I didn’t think this could be the issue.
A restart of the management services does not fix this. Only a reboot resolves this so far.
Hope this makes sense…
Any help would be appreciated
Cheers
Mike.
