Could not connect to the controller/invalid response from controller...

[CommunityUser]

I keep getting this in the logs:

"Could not connect to the controller/invalid response from controller, cannot get registration information"

I am on google213.saas.appdynamics.com

[paid108.saas.appdynamics.com]

From what I can tell, everything is setup correctly.

Hi,

Someone from our team will respond to your question, meanwhile could you please describe the issue in details which you encountered while trying to instrument your JAVA application and provide agent logs, if there are any.

Hi Jane,

I see that you are connecting to SAAS controller and by default controller is configured to receive requests as per listed 

HTTP->80

HTTPS->443

As per your earlier update, i do see that you are using port as 18090 as listed. So please use port as 80 instead of 18090 and also host name as SAAS controller host name but not 127.0.0.1

-javaagent:"C:\AppDynamics\AppServerAgent-4.2.11.0\ver4.2.11.0\javaagent.jar" -Dappdynamics.controller.hostName=google213.saas.appdynamics.com -Dappdynamics.controller.port=80 -Dappdynamics.agent.applicationName=ACMEOnline -Dappdynamics.agent.tierName=frontend_tier -Dappdynamics.agent.nodeName=frontend_node 

Thanks

Hi Jeff,

Could you check with the help of telnet / curl for the connectivity of the agent machine with the controller? Could you please let us know which agent you are trying to connect so we can tell you path of the log files to attach to this ticket. Another point to check is the AppDynamics configuration parameters like Application / tier / node name and there must be more so update them with your reply and we will verify.

Best Regards,

Piyush
