Steps - not reproducibe at 100%, happens from time to time:

1. ASSERT: have ~/.crc folder killed
2. EXEC: create new CRC server adapter & Start it
3. ASSERT: OpenShift connection is created
4. ASSERT: Connection fails to authorize, reports that it cannot access resources using system:anonymous.
5. EXEC: try to login with oc login. If oc reports Error from server (InternalError): Internal error occurred: unexpected response: 400, repeat until it succeeds (waiting required)
6. EXEC: Once oc login succeeds: refresh the connection in Eclipse

Result:
Connecting still fails with the same error.

Expected result:
Refreshing the connection should succeed once the server is fully up and running and oc succeeds to log in.

Workaround:

1. EXEC: edit the connection instead of refreshing it (ex. remove a character from username and add it back again)

Result:
Connecting succeeds
