It is not possible to submit an app in itunesconnect!

I already can't submit an app in itunesconnect! As soon as I check for errors or upload the file from Xcode, it just hangs and waits for a response from itunesconnect.

I was trying to send other applications and new versions of existing ones, the same is not working. Every time I post, Xcode starts to fall and close.

Tell me does anyone now the same problem?

Thank you very much for the reply!
