Hi Kiran,

Please let us know if there is any changes made on the controller side or the Agent side and then you started seeing this issue.

Could you please attach the provided the output of

Anybody know why the below error is coming? Is it the problem with the account? I am able to telnet the controller on port 80. The integration was working fine, now it stopped working.

Below is the error I am getting:

I am also facing the same:

 org.apache.http.NoHttpResponseException: blah.saas.appdynamics.com:443 failed to respond

Re: Unable to connect to the controller

CommunityUser — Tue, 03 Jul 2018 19:47:32 GMT

Interestingly, trying to load the failed url in the browser (controller/instance/0/applicationConfiguration), chrome gets an error:

blah.saas.appdynamics.com didn’t send any data. ERR_EMPTY_RESPONSE

So I suspect the problem is on the controller end 😕

Hi Josh,

We need the exact SaaS URL you are hitting to check if there is an issue with the SaaS controller. Could you provide us the correct SaaS URL?

-Thanks

Hi, Can you share (telnet <controllerhostname> <controllerport>) from agent host provide controller host and port used in the agent config? and also send the agent node logs folder archive for our review, email logs directly to my email id shared email in a different message.
