I deployed the Marketplace version of Mattermost, but I can't get it working with https.
I’ve gone through the setup steps a number of times, trying recommended settings for a proxy pass-through using nginx.
I’ve got my domain set up, and the droplet has a LetsEncrypt certificate (via certbot), which produces an A rating from www.ssllabs.com/ssltest/. But the only configuration I can get to work for the app itself is to use http and the mattermost default port of :8065.
I seem to be caught in a catch-22 between Mattermost SSL configs and the droplet’s nginx configs, and perhaps how certbot alters the nginx configs.
I’m happy to do more legwork if you could point me at any other guidance about using https with the Marketplace implementation of Mattermost (which I very much appreciate).
