I set a 30-second timeout to avoid timeout requests from the App Store Connect API service. So I wonder if there is an exact value for the official timeout. But your answer is very helpful to me, I can retry three times to ensure that the service is normal. Thank you very much.

I last Thursday via https://developer.apple.com/contact/topic/select sent apple email, until now all have no reply, if you have any good way which can contact to apple, trouble also say with me

I have sent several emails to Apple officials, so far I see that the interface has returned messages normally
