So I have the following setup:
[INTERNET] ===> [NAT ROUTER] ====> {REVERSE PROXY} =====> {MATTERMOST}
but how do I set it up properly so that any port 80 or port 443 communications are properly sent over to the Mattermost server?
Right now, I have tried setting up the URL in Mattermost and enabled SSL communication (certbot is installed on the Mattermost server), but this results in an SSL error (which I can override) and then displays NGiNX default page.
