I've been trying to upload my xamarin.iOS app to app-store-connect several times during the past couple of days. I have been using Visual Studio for Mac's Sign and Distribute window to upload the app to app-store-connect without any issue, until a couple of months back.
Checking my network activity, it shows that the app is being uploaded. But the app distribution window didn't show any response.
Then I used the Transporter app to upload the app, and it also didn't go well. (Check the error logs)
An exception has occurred: java.net.UnknownHostException: contentdelivery02.itunes.apple.com: nodename nor servname provided, or not known
An exception has occurred: org.apache.http.NoHttpResponseException: contentdelivery02.itunes.apple.com:443 failed to respond
java.net.UnknownHostException: contentdelivery02.itunes.apple.com: nodename nor servname provided, or not known
org.apache.http.NoHttpResponseException: contentdelivery02.itunes.apple.com:443 failed to respond
For me, it looks like there is an issue with the Apple servers.
Any thoughts?
