Problem

When trying to edit a page in Confluence, you see the following error:

The editor didn't load this time

The connection timed out. If it happens again, speak to your Confluence admin. You may be using a proxy server that prevents WebSocket connections.

Diagnosis

Environment

You may encounter the error if you're using either:

• A proxy server that doesn't allow WebSocket connections
• A firewall that doesn't allow WebSocket connections
• Confluence Cloud with an older, unsupported web browser, which doesn't support WebSocket connections
• Confluence Server with an older, unsupported web browser, which doesn't support WebSocket connections

Diagnostic Steps

• Test WebSocket connections by using https://websocketstest.com/ to perform a quick HTML5 WebSocket test against an echo server.
  
  
• If possible, connect to a different network that doesn't use a proxy server

Cause

Collaborative editing in Confluence requires a WebSocket connection. If one can't be established due to a timeout, or a proxy server or firewall that doesn't allow WebSocket connections, the editor will fail to load.

Resolution

As collaborative editing requires a WebSocket connection, the possible resolutions are:

• Use Confluence Cloud with a supported web browser
• Use Confluence Server with a supported web browser
• Configure your proxy server to allow WebSocket connections
• Configure your firewall to allow WebSocket connections
• Remove the proxy server from your network configuration

• For Confluence Server – Turn off collaborative editing
