Connection to codecademy frequently drops due to websocket errors

Connection to codecademy frequently drops due websocket exceptions.
I’ve noticed that after after some time spent on codecademy (working on js course at the moment) the connection to codecademy starts to glitch and site constantly asks me if I’m still there, which is frustrating and distracting from learning process.

It seems that it is not firewall or internet connection issue since in console I see the repeating message like this:

Uncaught (in promise) DOMException: Failed to execute ‘send’ on ‘WebSocket’: Still in CONNECTING state.

The only workaround is to refresh the whole page which, as I’ve said is frustrating and distracting.
Another one thing that disturbs me is that you guys are teaching programming, while your own platform is not stable, which brings obvious questions - are you really can teach other people this stuff?

Hi there, this seems like a good question for our customer support team, whom you can reach here.

Thank you Daniel!
