Cannot connect to vCenter Server via vSphere Client – timeout

I’ve been upgrading my company’s solution centre to vSphere/vCenter 6.0 update 2 the past week and noticed that I was having issues logging into the vCenter Server Appliances I had deployed.

It was a strange issue because I could log into the Windows vCenter Server I had deployed in my primary cluster, but couldn’t log into the vCenter Server Appliance I had deployed in my secondary cluster….. hmmm…. Web Client worked fine for both, but it was the vSphere C# client that was timing out for the vCSA!

After much head scratching and trawlling through logs (Found at C:\Users\username\AppData\Local\VMware\vpx\viclient-x-0000.log), it turns out the problem is with the default time out value of the vSphere client for authentication.

The default timeout value is 30 seconds, and my suspicion is that the vCSA was taking slightly longer to respond to authentication…. changed the value to 60 seconds and it all worked fine!

Fire up vSphere Client and connect to another vCenter Server or ESXi host, then click Edit->Client Settings. Change the Client-Server Command Timeout value to Use a custom value and the Timeout in seconds to 60.

Here’s the VMware KB article about timeout values: https://kb.vmware.com/kb/2072539, there’s also instructions on how to edit the Windows registry if you can’t bring up vSphere client.

Just for the sake of it, here’s the error log:
