MWS 9.5 is not starting when using custom certificate for HTTPS

Given a fresh installation of MWS 9.5 SP1 without Fixes.

When trying to configure HTTPS by using a custom certificate instead of the demo certficate, the MWS is not accessible due to the fact that it was not possible to decrypt the certificates.

This worked on another environment the same way, but not on this one.

Any Ideas?

Can you provide more details about the error?
Is it happen when bringing up the server or when client try to access the web UI?

This happens during startup of the MWS.

Even the HTTP Port is not working when this occurs.

One thing might be that the private key has not been created on this zone where MWS is now installed but another.
