Intermittent “Connection Failed with IP Address” Error in Azure API Management

Hello,

Over the past few days, we’ve observed that our Azure API Management (APIM) instance intermittently throws an error for a few minutes and then resumes normal operation without any intervention.

Upon investigation, I found the following error in the logs (End-to-end transaction details):

“Connection failed with IP address”

Interestingly, after a few minutes, when I ping the same IP address, it responds as expected.

I’m trying to determine which resource is associated with that IP address, but haven’t been able to identify it yet.

Could you please help me understand:

How can I identify which Azure resource is linked to that IP address?

What could be the potential root cause of this intermittent connectivity issue?

What’s the best approach or recommended solution to prevent or troubleshoot this type of issue?

Thank you for your assistance!

Best regards,

Vijay
