Cannot connect to Controller

[CommunityUser]

Might be very basic configuration problem. I see the controller is up and running and agent is also configured properly with controller's ip.

Current Node

But in agent log I see the below exception.

Hello have you correctly configured the Account key in the
controller-info.xml file?

[CommunityUser]

I gave account-name and account-access-key as the user name and password that I use to login to controller UI. Is that correct?

[Raunak_Mohanty · Accepted solution]

Please provide account name and access key based on following document link
