ERROR - "vSphere Client could not connect to (IP/Server) An unknown connection error occurred. (The request failed because of the connection failure. (Unable to connect to the remote server)) ..."
All has been running fine for several months BUT now unable to connect to esxi 5 with vsphere client.
-network passes Test Management Network
-Management Network restarted
-Management Agents restarted.
Worried about restarting esxi host in case I am still unable to connect with vsphere to launch vm (sbs 2011 currently running with rdp access)
Any changes in the environment? Any firewalls between the client and the host? Make sure ports 443 and 902 are not blocked.
Just to clarify, are you attempting to connect directly to the ESXi host or to vCenter? If you are trying to connect to vCenter, restart the VirtualCenter services.
Have you tried loading the client on another machine?
homerzzz - thanks for the response.
No changes to network, I had both network and remote vSphere access direct to ESXi host (not vCenter) up until a week ago.
Checked ports 443 and 902 and not blocked.
vSphere loaded on two other Win7 PC's - still no luck.
Also tried VMware® Workstation 12 Pro "connect to remote server" - still no luck.
I can ping the host but cannot browse or connect with vSphere. only have DCUI access.
Could it be that your SSL certs are giving you an issue? You can try to regenerate them by following this:
You typically generate new certificates only if you change the host name or accidentally delete the certificate. Under certain circumstances, you might be required to force the host to generate new certificates.
