Hi Jorge,

Have you checked that Wily Enterprise Manager is working and the logs for same ?

Please check if below SAP note helps -

1559812 - Unable to connect to Wily Introscope Webview or Wily Introscope Workstation because of err...

Thanks & Regards

Hi Jorge,

Try reinstalling the local Java on the machine where you're running Introscope.

Also something I recommend you to consider is installing the Introscope Workstation client locally on this machine. I've had a way better experience on using this client than the webview option through port 8081.

For more information follow the instructions on the installation guide referent to your Introscope version.

Good luck!
