Issue/Introduction:

After upgrading from APM 10.2 to APM 10.5 we cannot use 8443 port as the Enterprise Manager web server Secure Port as connecting to the web server home page gives an http 500 server error. If we use a different port i.e. 8444 it works ok.

If we enable DEBUG logging in the Enterprise manager we see the following at the point of failure.
