Expected behavior

We have a subscription for Application Insights and I'm trying to send the telemetry data through Eclipse IDE. But I'm getting a 'Connection refused' error: eastasia-0.in.applicationinsights.azure.com/[0:0:0:0:0:0:0:0]:443

Please find the applicationinsights.log for more information.

I am not sure where is the problem, is it with the applicationinsights server or was it something to do with the our "connectionString" I have specified. connectionString seems to be correct which I have copied from the Application insights dashboard.

Any help on troubleshooting would be appreciated!

Actual behavior

It should send the data to the server

To Reproduce

• Downloaded an eclipse ide
• Downloaded applicationinsights-agent-3.4.0.jar
• Added -javaagent:/Users/xx/esp/applicationinsights-agent-3.4.0.jar
• Created a file applicationinsights.json in the same folder as agent jar and added the required content as mentioned in the doc.
• Started an eclipse
• However, I see it was unable to establish a connection to the server and not sure what went wrong.

System information

Please provide the following information:

• SDK Version: Java agent 3.4.0
• OS type and version:macos arm64
• Application Server type and version (if applicable): Java using eclipse-ide
• Using spring-boot? NO
• Additional relevant libraries (with version, if applicable):
