"Could not complete the request" when testing API, even with default EchoAPI

Question

I got "Could not complete the request" when testing API, even with default EchoAPI. There's no other error messages, so it's hard to debug

Answer 1

Thanks for posting your question in the Microsoft Q&A forum.

Here are some steps to troubleshoot and potentially resolve the issue:

• If you're connected to a VPN, try disconnecting from it and test again. VPNs can sometimes interfere with the connection or modify certificates, causing this error
• If your APIM is deployed in a VNET, ensure that the NSG rules and route tables are configured correctly to allow connections from external clients, including the Azure portal
• Try accessing the API URL directly in a browser like Chrome. This might provide more detailed error information
• In some cases, security services like Microsoft Defender for Cloud Apps can create a proxy that intercepts requests. Check if you see "portal.azure.com.mcas.ms" in the request domain
