Issue/Introduction

Getting the following error after connecting to APMIA with SAP_Hana over EM connection. Here is what I get in the debug log. I will attach to the case all the logs

 [VERBOSE] [IntroscopeAgent.ConnectionThread] Attempting to connect to Introscope Enterprise Manager 10.37.7.93:5001,com.wily.isengard.postofficehub.link.net.HttpTunnelingSocketFactory (61).

Resolution

Took a quick look at the profile and I see the following 

 

agentManager.url.1=http://10.37.7.24:5001

 

wondering if you could try with the following settings i.e. without http:// and restart.

 

agentManager.url.1=10.37.7.24:5001

 

Additional Information

There are a lot of other possible causes of this error such as connections not released. Expecting https not http, etc.
