Websocket or network connection blocked

Websocket or network connection blocked

This is a technical article designed for IT or Networking professionals.

To ensure Joinin works correctly it is important that the connection between your web browser and Joinin is not blocked. Joinin relies on WebSocket connections for real-time communication.

A blocked connection can be caused by:
  1. AdBlocker / Cookie blocker browser extensions
  2. Antivirus and Firewall software
  3. Proxy and VPN connections

Solution

Browser extensions

  1. Firstly, try using Joinin with Google Chrome, instead of another browser.
  2. If you are already working in Chrome, try the Guest mode in Google Chrome. This disables any extensions in use.
If you no longer see connection errors after these steps the cause is probably a browser extension that is blocking websockets. Try the following:
  1. Disable your browser extensions one-by-one and try Joinin each time. This will help determine which extension may be causing the issue.
  2. In some extensions, you can configure what domains to block or allow. Remove or add the following domains to that extension: 
*.joinin.live
*.pusher.com
*.xirsys.com

Antivirus & Firewall

If you still see connection errors in Guest mode of Google Chrome, your antivirus or firewall may be the cause.
  1. Temporarily turn off all antivirus or firewall software, or try a device without this software (for example an iPad).
  2. If the error is solved, your antivirus or firewall is probably the cause.
  3. We cannot determine which specific antivirus or firewall software is blocking websocket connections. Please ask your IT manager to allow websockets from the following domains:
*.joinin.live
*.pusher.com
*.xirsys.com

VPN & Proxy servers

If you still experience errors, it is likely being caused by VPN connections or a corporate proxy server. Please ask your IT manager to allow websockets from the following domains:
*.joinin.live
*.pusher.com
*.xirsys.com
