Hi When I try to validate an ipa with altool by running xcrun altool --validate-app \ --file app.ipa \ --type ios \ --apiKey $APP_STORE_CONNECT_KEY_IDENTIFIER \ --apiIssuer $APP_STORE_CONNECT_ISSUER_ID \ --show-progress \ --verbose \ --output-format json it keeps failing with the following error: Altool error Now, at first glance it looks like this could be some one-off issue which should be resolved by a simple retry, but actually the same thing happens over and over again. We have tried it on different macOS hosts, with different Xcode versions and different Apple Developer team credentials even. Verbose altool log output is also very consistent. The failing request is always to https://contentdelivery.itunes.apple.com/WebObjects/MZLabelService.woa/json/MZITunesProducerService. Relevant log portion is as follows: Altool verbose error log What could be the issue that is causing this? Best regards
