Expected Result:

websocket Menu should be available

Any Workarounds:

do not check the option: "Configure WebSocket Proxy for selected server/websites"
applying a working websocket.xml will not fix the issue.

Is there any other possibility to revoke this setting without reinstalling the ColdFusion Server?

Hi Oliver,   Can you follow the below steps? # Replace the neo-websocket.xml with a working copy? Make sure the proxy port in this file is similar to the proxy port being seen when wsproxyconfig tool is run # Restart ColdFusion   Thanks, Kailash

Yes, worked. The ColdFusion Server has to be restarted directly after replacing the neo-websocket.xml. If Websocket Menu is selected before Restart, neo-websocket.xml goes blank again.
