Been facing this error in agent log. Browser RUM data ok via injection into header of html files. Application monitoring shows connected, but no data received.

Hi Loong.Ang-

If you are not running the Network Visibility Agent, can you please disable socket instrumentation (netviz) using the below node property and then restart the application agent:

Name: socket-enabled
Description: socket-enabled
Type: Boolean
Value: false

 Note that you may need to manually create this node property if it does not exist. Information on how to edit a node property can be found in the following link:

https://docs.appdynamics.com/display/PRO45/App+Agent+Node+Properties

This error should not impact your application monitoring. If you edit this node property and are still having issues with the application monitoring not receiving data, it may be best to escalate directly to AppDynamics support:
