Fix "Websocket connection blocked" to access HTTPS over RDP​

Possible reasons​

  • AdBlocker / Cookie blocker browser extensions
  • Antivirus and Firewall software
  • Proxy and VPN connections

Solutions​

  1. If you are already working in Goole Chrome, try the Guest mode. If you still get the error even after using Guest mode of your browser, your antivirus or Firewall may be blocking it.
  2. Temporarily turn off all antivirus and Firewall programs, or try a different device (for example an iPad).
  3. If the error is fixed, your antivirus or Firewall is probably the cause.
  4. If you still get the error, it may be caused by proxy or VPN connections.
  5. In such a situation, we can't determine which specific antivirus or firewall software is blocking the websocket connections, or the steps to prevent this from happening. Please contact your IT manager.
  6. If you still get the error, it may be caused by proxy or VPN connections.
