Unable to connect to the controller

[bkirankumar]

We connect to Appdynamics to SaaS controller on port 80, I was able to send application data to Appdynamics earlier and it was working fine. Now I see below error in logs,  please advise.

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 complete agent log folder. Along with that provide the output of 

shell > curl -v https://<domain-name>.saas.appdynamics.com:80 or ping command output.

Thanks,

Yogesh

Hi,

Could you please attach the agent log as we could see it is missing in your earlier post.

Thanks,
