Cannot talk to the controller

CommunityUser — Sun, 30 Dec 2018 10:56:28 GMT

This is the error that I get below. I have turned off SSL and I am connecting to the SaaS controller on port 80. I can connect fine via my internet browser.

The application is a Java App and using a Jboss.

Where am I going wrong and what do I need to change to resolve this error?

Hi Richard,

Thanks for posting the question on the Community.

Could you check your agent server’s firewall outbound setting? You need to allow outbound connections for these IP range:103.28.248.0/22 for your SaaS controller. This is documented in here: https://docs.appdynamics.com/display/PAA/SaaS+Domains+and+IP+Ranges

If it does not work, could you share your complete log directory?

Many thanks,

Naoto
