Losing DDP connection


#1

I have a web app that is actually split in 2 Meteor apps, one for the logic, the other one for the UI. Both are communicating via DDP.connect. It was working well, but since a few days, my UI app get disconnected from the logic app after a couple of minutes. I just need to restart the “logic” app and it works, but 2 minutes after it disconnects again.

I really don’t know how to debug this problem. Any help would be great!

Here is the websocket messages from Chrome dev tools:

I see a last ping, then no “pong”. I don’t know what to do…
