Veeam backup not able to connect to ESXi 5.0 Host

I'm receiving the attached message when trying to connect to an ESXi 5.0 host.

I am able to connect to my ESXi 4.1 hosts with no problems, just something with 5.0?

I have tried to connect to this host from Veeam by adding the VCenter it's managed by and I get the same error.

Any ideas?

Thank you

Have you made sure the proper ports are open and/or disabling the firewall?

Can you connect to this ESXi 5.0 server via the vSphere Client?

root password correct?

ESXi 5.0 running okay?

Yes, I have confirmed all the ports are open.  Also yes, i can connect via VSphere client with the root login account. I retyped the password numerous times.

Yep, 5.0 is running fine.  No alarms or anything.

Wish it was as simple as a typo:)

it may be worth just restarting network management agents

Ok I just did a telnet to that host using port 902, it connected successfully.

I tried with port 443, it just goes to a blank screen. Then goes back to the dos prompt.  i'm thinking this may be the problem.

But not sure where to fix this, I looked in Security Profile and 443 is open?

Restarted the network mgmt agents, still no luck.  And I realized that seeing a blank screen with a cursor is normal when telnetting to a specific port.

I'm not finding much on the internet for this either.
