I am trying to setup mattermost with a Lets Encrypt cert and run on 443. I have the cert working but if you use the siteurl it goes to the Apache server and not mattermost.
Please help with any additional relevant information for troubleshooting including any log errors and config settings along with the details from this page: https://docs.mattermost.com/process/support.html.
I think I have narrowed it down some by looking at the logs for mattermost.
listen tcp :443: bind: address already in use
not sure where in apache I may need to make a change
