502 Bad Gateway with MM-Omnibus


I am new to Matter most. i have recently built a Matter most with Omnibus server. with nginx. I have setup SMTP, and it was working until I tried to restart it after configuration changes. Now I get an 502 bad gateway when trying to load the page. I am more then willing to provide the logs if you can direct me how to get them posted. Again sorry for noob questions.

I also get this from the console when I try to edit the local config file

Error: socket file “/var/tmp/mattermost_local.socket” doesn’t exists, please check the server configuration for local mode
