Apache and Tomcat default ports with websocket transport - Atmosphere/atmosphere GitHub Wiki

Apache and Tomcat default ports for non-SSL environment web sockets are getting closed out, this behavior is observed in both apache fronting in load balancing or tomcat running as standalone.

will notice an error at client side

?X-Atmosphere-tracking-id=0&X-Atmosphere-Framework=2.1.2-jquery&X-Atmosphere-Transport=websocket&X-Atmosphere-TrackMessageSize=true&X-Cache-Date=0&X-atmo-protocol=true&selector=' failed: Failed to inflate a frame jquery.atmosphere.js?bust=V5:928

Cause was end user machine of the web socket application having Trend Micro agent running.

I have found that trend micro agent also monitor and use default ports like 80 and 8080.. internally which is closing out

you have three options to overcome this problem :

  1. turn off trend micro agent

  2. there are ways to change trend micro default ports

  3. change the port on apache /tomcat from 80/8080 to 800/8081 like that it works fine.
