There's no Mattermost category yet, if one is created please move this post
I've setup a Mattermost install to Google Compute engine. Everything worked very well except that I can't get nginx to use my letsencrypt SSL certificates. You can find my full config in this GIST. Note, I have replaced the standard ssl certificate path in /opt/bitnami/apps/mattermost/conf/certs/server.crt to the standard letsencrypt path. NGINX doesn't seem to recognize the certificates. Copying the certificates over to the standard files doesn't work either. I've also tried enabling SSL directly in mattermost but then NGINX can't connect to the backend anymore. The error log doesn't have any meaningfull error in it.
Any idea what the problem could be? Thanks!
