Hi Pablo,
As far as I can see in the screenshot, it looks like you are having problems loading the simulation (not the IDE, as you mentioned. The IDE [code editor] is the screen in the middle).
There seems to be something in your browser blocking the page. Please check:
- Is your browser in incognito or private mode (or some other limited mode)?
- Does your network allow WebSocket connections,
ws://
orwss://
, in addition tohttp
andhttps
? We use WebSocket extensively for those screens. You can check whether WebSocket is working here: websocket. - Is third-party JavaScript enabled for your browser?
- Are you using an AdBlock or some strict Internet Security suite?
- Are you behind a VPN/Firewall?
A quick troubleshooting step is trying another browser (we support Chrome, Edge, and Firefox), an Internet connection, or a PC you have not tried before.
