Interpret URL correctly which port is the webserver listening to? [closed]

Solution 1:

Yes, it is quite simple.

The ports you assume (443 SSL) are DEFAULT. The URL overrides it. Done.

It goes with https to port 7535 and the server listens to that port with the ssl certificate. The SSL certificate HAS NO PORT NUMBER IN IT.

so i always thought the webserver is listening on 443

That is the default. Clearly the default is changed in the server configuration, though the server may ALSO listen on port 443 - you could test that.
