Troubleshooting
1

Summary

I am using mattermost on a Digital Ocean Droplet with a Digital Ocean managed postgresql database. I am unable to ping that database.

this is the sql settings for my config.json

  "DriverName": "postgres",
  "DataSource": "postgres://mmuser:mmuser_password@do-server:5432/mattermost-db?sslmode=require&connect_timeout=10",

Expected behavior

To connect sucessfully.

Observed behavior (that appears unintentional)
