Various SSL errors while using VMware Web Client or vClient

Abstract

Many errors can occur while using a misconfigured VMware Web client or vClient. Below you can find the errors I found. Explanation and solution for some SSL errors.

Opening console from Web Client

Thumbprint mismatch SSL error

SSL verification failure for "vcenter1.example.com" due to a host thumbprint mismatch: stored thumbprint "8d:29:ae:69:87:e5:cc:a0:ff:01:51:25:84:8a:b4:d3:b5:a3:55:33" does not match certificate thumbprint "5B:E9:36:23:44:F0:4D:E5:6A:F3:7E:BC:4F:FE:9D:0D:93:64:03:E0".

Opening console from vClient

Unable to connect to the MKS error

Unable to connect to the MKS: Login (username/password) incorrect.

or

The server name could not be resolved

Deploying an OVF/OVA from Web Client (after selecting the datastore):

Unable to establish an SSL connection error

Unable to establish an SSL connection with vCenter Server

or

Unable to validate that the OVF can be imported on the vCenter Serve

Solution

The most common reason of all above errors are hostname resolution. Be sure the client where Web/vClient is running, has the same hostname resolution of vCenter. In other words be sure that clients and vServer are using same DNS servers. Be sure you also check hosts file.
