Hi,

I’ve replied to the ticket you also opened. Let’s keep the conversation in one place (on the ticket).

For completeness, I’ll repeat the same response here:

MongoDB won’t be on 0.0.0.0, you’ll need to ensure the hostname for your Mongo server is correct.

If you have a MongoDB instance on Atlas, then they will provide the connection details (the host will likely end with ...mongodb.net)
