I see... thanks Peter. Yeah, I was trying to follow these instructions:

But also including the instructions from the main site:

I just tried what you recommended (using the port 443 only) and the problem
went away. I'll give it a thought and see which port / configuration might
be the better one.

Oh, and I configured a CDS to practice and learn a bit. It might be
implemented in the end (probably not), but now I have some idea of how to
make it work, just in case.

Thanks for your help guys.

Christian Munive.
