Current Mongosh Log ID: 62a418c7740d6e8837461793
Connecting to:          mongodb://127.0.0.1:27017/?directConnection=true&serverSelectionTimeoutMS=2000&appName=mongosh+1.5.0
MongoNetworkError: connect ECONNREFUSED 127.0.0.1:27017

Changing the ownership of these files helped me.

sudo chown -R mongodb:mongodb /var/lib/mongodb
sudo chown mongodb:mongodb /tmp/mongodb-27017.sock
