This is my first HTTP server setup. I am configuring the IBM HTTP Server 8.5.5.14 to serve as a reverse proxy for a Rational CLM 6.0.6 implementation that is distributed across several Windows Server 2016 virtual machines.
I have read the work instructions here and have provisioned the SSL certificates. When I modify the httpd.conf file according to the work instructions, the HTTP server doesn't start and the system event viewer logs:
(OS 10048)Only one usage of each socket address (protocol/network address/port) is normally permitted. : make_sock: could not bind to address 0.0.0.0:443
I narrowed it down to the guidance in the work instructions that says to add:
Listen 443
When the httpd.conf already has:
Listen 0.0.0.0:443
Note that the work instructions indicate that BOTH listens should be in httpd.conf.
However, when I comment "Listen 443", the server starts and is accessible via HTTP but returns ERR_CONNECTION_CLOSED when accessed via HTTPS.
Any thoughts? Thanks in advance!
