Websocket/Editor not loading

When I try to open my editor its stuck on fetching project and in chrome console it shows this:
VM1501:164 WebSocket connection to ‘wss://api.glitch.com/hd-bot/ot?token=myToken’ failed: Error during WebSocket handshake: Unexpected response code: 502

How can I fix this?

Edit: I had a backup on my pc so I created a new project and it works now.
