I frequently get errors like “WebSocket connection to ‘wss://msg.playcanvas.com/messages’ failed” and “net::ERR_BLOCKED_BY_CLIENT” when using PlayCanvas. How can I fix these connection issues?

Which browser are you using? Do you possibly have any extensions or desktop software (e.g cybersecurity software) that could cause these net::ERR_BLOCKED_BY_CLIENT issues?
Could you try this in a clean browser setup and see if these issues persist?
