Answer 2

I have never encountered a similar error, but I searched stackoverflow and found posts with similar problems:

http://stackoverflow.com/ques...

The problem is probably related to the instability of the network, so one method in the post is to modify the connect options:

var options = {
server: { socketOptions: { keepAlive: 1, connectTimeoutMS: 30000 } },
replset: { socketOptions: { keepAlive: 1, connectTimeoutMS: 30000 } } }
};
mongoose.connect(secrets.db, options);

For reference.

Have a great weekend!
