Error: getaddrinfo ENOTFOUND api.appcenter.ms api.appcenter.ms:443 throws on uploading files to appcenter - junit

Question

I am working on sample tests for mobile application and to upload and run in AppCenter. I have tried with XamarinUITest and C# combination; test files uploaded and ran successfully. On trying test files with Appium, Java and Junit and tried to upload it in AppCenter throws Error: getaddrinfo ENOTFOUND api.appcenter.ms api.appcenter.ms:443 in Terminal.
The snippet I am using to upload is:
appcenter test run appium --app "Appium/JunitiOS" --devices "Appium/iphone" --app-path pathToFile.ipa --test-series "test" --locale "en_US" --build-dir target/upload
Note: given corresponding file paths in the snippet.
and get the below in Terminal:
Preparing tests... done.
Validating arguments... done.
Creating new test run... done.
Validating application file... done.
Uploading files... failed.

Answer 1

This error usually occurs when there's some sort of network issue (either WiFi dropping out, a corporate firewall or proxy or a DNS issue are likely culprits)
Things to try if the successful upload is running on a different machine or a different network
Check the failing upload over a different network
Make sure you can see the URLs and IPs from the machine you're running on
If that fails - reach out to support using the App Center portal and a support engineer will help you get up and running
Things to try if the successful upload is running on the same machine on the same network
Double check that the UITest tests are still working successfully
Check that you don't have any corporate firewall policies which could be blocking specific files
If that fails - reach out to support using the App Center portal and a support engineer will help you get up and running
I would also recommend running the command again using --debug - you should be able to see the API calls being sent and identify at which point the uploads are failing (and if it's the same point every time).
