I just installed mattermost and want to enable traffic over TLS using my own SSL certificate. I moved my private key and full chain certificate files (`private.key` and `fullchain.crt`) in this path: /opt/mattermost/ssl and edited config.json like this:  
“ListenAddress”: “:443”,  
“ConnectionSecurity”: “TLS”,  
“TLSCertFile”: “/opt/mattermost/ssl/fullchain.crt”,  
“TLSKeyFile”: “/opt/mattermost/ssl/private.key”,  
but after restarting service, I get error and service status is down. what did I wrong?

What does `systemctl status mattermost.service` say? My first guess is permissions issues on your cert and key files.
