I can't connect to an ESXi 5.0 update1 host via the sphere client. I can connect to vCenter with no problems, and I can RDP into the VMs on the host with no problems.  I can ping the host using the DNS name or the IP address, i can access the host via DCUI, but when I try to connect to the host via the sphere client I get the following error.

I as a result i can't add this host to vCenter either. I reset the host management agents, the management network also. I ran network test in the host's DCU and everything thing came back "Ok" with the DNS, Gateway, and Hostname. This issue started today, when there was a network issue and I believe the host became isolated (disconnected) and it's VM (disconnected), so I removed the host from vCenter and logged into the host via DCUI and reset the agents. The host and VMs were now pingable, but I can no longer access this host via the vsphere client nor can I add it to vCenter. Nothing changed in our network. I didn't try to reset this host since the VMs where running fine. I need to get this host back into vCenter so does any one have any ideas on fixing this? Thanks

telnet to the following ports

telnet 172.16.3.8 80

telnet 172.16.3.8 443

telnet 172.16.3.8 902

also try

http://172.16.3.8 

do they connect?

are you using the same IP Address which is displayed on the DCUI (console screen).

perform the above from a workstation and the vCenter Server.

Yes the management port is the same and has not changed.

yes https://172.16.3.8 does connect, but I cannot telnet into 80 or 443.
When I telnet into 902 I get this message:

Port 80 and 443 give absolutely no response, but the image is the response of 902

if http (port 80) connects and you get a web page - response is okay.
902 - that is the correct response.

check any firewalls, of group policys that have been defined, that block 443. Recently we had an issue where a vCenter Server had been moved to different AD OU, which had a firewall policy which cause this issue.

Port 443 is the port which the vSphere Client connects on.

Restart the Hosts.

Strangely enough. I started working again. I didn't do anything, also of a sudden, i could connect via the vsphere client. I just joined it back to vCenter also with no problems. That was really strange, but thanks for you replies.
