Got stuck while uploading ipa file to app store connect

I was successfully uploading .ipa file to App Store Connect after archiving my swift project until yesterday, but after doing some minor changes i wanted to upload again and it always gets stuck at this point and it does not progress for hours.

I know my upload speed is slow, the thing is why suddenly it stops at this point and does not progress? I did upload 4 times before this happened and there was no problem.

Solution

My problem is solved now, it was related to a problem with my ISP. Because network was so slow, sometimes connection was restarting and it got stuck.
