Usually, to start / stop listeners or agents, we would navigate to Admin studio -> Resources -> Listeners or Agents. But after today's restart, Admin studio is not responding upon click of listeners under resources tab. Only change that was made to the application was to enable couple of DSS (submitobfuscatedurl and urlencryption) to solve cross site scripting XSS vulnerability. Also, below log entries are present everytime we try to access Adminstudio->Resouces->listeners. Can anyone please help to highlight what is causing this issue and how to solve this.
