If the proxy started but you don't have a connection to the Controller, you may be using incorrect Controller information.

Examine the proxy log and verify that there are no typos in the Controller domain name or port and that SSL setting is enabled for an SSL connection. If there are mistakes, edit the Controller/port/SSL values in the configuration. These settings are on the first page of the Agent Download and Install Wizard or the agent settings if you installed the agent manually.

If you have verified that the Controller settings are correct and the proxy still does not connect to the Controller, telnet to the SaaS Controller:

telnet <your_account>.saas.appdynamics.com 443

If you cannot access the Controller through telnet, examine the agent-registered messages in the logs that indicate why the proxy is unable to connect, such as the existence of a firewall or other obstacle at your site. Work with your administrator to see if you can resolve the issue.

If you can reach the Controller through telnet, there may be a problem on the Controller.
