IDE loading Issue - Error Code 1200

[Rudraroop_Ray]

The IDE has stopped loading. It was working just fine last week when I was doing the M001 Basics Course but now whenever I open a lab assignment and try to launch the IDE there’s an error message saying "There was an unexpected error. (error code:1200). Screenshot attached. What do I do to resolve this? Haven’t changed anything in my system or browser since the last course.

Hello there,

I have the same issue. It is related to WebSocket connection which unfortunately can’t be established successfully.
In logs I found:
wss://mide.mongodb.com/environments/connect?course=M103&problem=deploy_replica_set&image_id=mongodb-4.0
There was a bad response from the server.

Hope it helps

Just a note that this can also happen if you have the IDE open in another browser tab. (As I am wont to do. )
