Meteor Client not syncing with server

I have a collection running on a device and the app is pointing to a meteor server
host:3000. The server has an external mongoDB. I have subscribe and publish methods in the code
when I update the record on the device the external mongo(where the meteor server is pointing)
is not being updated.
Any suggestions

Can you narrow down the part that’s not working?

  • is the request heading our to the external Mongo?
  • firewall?
  • try different network connection?
  • what is your mongo_url? is it formed correctly?
  • can you connect to the the mongo db using the mongo client?

I meteor deployed on a host as a web app,
I also have a meteor app on my mobile device, The app on the web uses monad_url and works but the one on the mobile I built it using --mobile-server host. How can I make the one on the mobile app point to external mongo DB and I like it to sync automatically with my local mongo on my device
