firewall problem: XCode upload app to App Store Connect

Hi All,

When I use XCode to upload app to App Store Connect with my company network. I get error. The log shows "Error Domain=ITunesConnectionOperationErrorDomain Code=-19000 "The server returned an invalid response. This may indicate that a network proxy is interfering with communication, or that Apple servers are having issues. Please try your request again later..."

I am sure it is my company's firewall problems. because when I change to use my cell-phone's mobile network, I can upload successfully.

Can anybody tell me how to set the firewall. My company has already allowed *.app.com, but still not work.

Thank you very much.
