WSSA not connecting over UDP causing performance issues

Products

• Cloud Secure Web Gateway - Cloud SWG

Issue/Introduction

Users running WSS agent cannot connect into WSS using the preferred UDP transport, and always seem to use TCP

WSSA performs better when connected over UDP. Users can have degraded performance with TCP.

Environment

WSS Agent on Windows/MacOS

Cause

WSSA connecting using TCP instead of UDP.

Resolution

Check if user has an antivirus which can block UDP connections from wssad.exe. Make sure wssad.exe is not being blocked by an antivirus for UDP connections. You may ask your AV team to see if its needs whitelisting/exceptions.

Check if there can be any other host/network based firewall in the path which can block UDP and allow accordingly.
