Server stopped after upgrade (SOLVED)

FINAL Fix

Remove TLS from config.json

Summary

After running latest upgrade procedures that I have noticed it changed a bit from the previous versions…

Never had seen such a issue before this upgrade.

Other changes done were to replace platform with mattermost in mattermost.service

Steps to reproduce

Running on Centos 7, with MYSQL 5.7 and nginx Proxy 1.14.0
Using 5.1.0 and had previously version 5.0

Expected behavior

Mattermost must be accessible behind the proxy.

Observed behavior

Problem solved, since it was caused by the TLS in config.json .

To be honest this TLS/SSL stuff and not knowing what and how to do best config is confusing. Would like to see improvements here.
