After updating OMSA on the hosts (running ESXi 5.5) to version 8.3.0 I get the following message (when attempting to log in via the server administrator portal):

"Server Administrator Web Server Version 8.2.0 is not supported with this Server Instrumentation Version 8.3.0..."

Tying to access other hosts with OMSA remotely, I am getting 'internal error' after the logon attempt. This was working prior to the update. I am also not able to log in to the "Manage Web Server" link in the Managed System Login page.

Is this a Tomcat update that is needed or something else entirely? Any advice would be appreciated.
