10.2 MCP Server Unreachable

Hi, 

Before upgrading to 10.2 the MCP server was reachable by default at 

https://mydomain.com/Thingworx/mcp

now after upgrading to 10.2 it returns HTTP status 400 - Bad Request.

Is there anything needed to be done during configuration/installation for 10.2 that could have been missed? Thank you.
