Apple Transporter failing to upload IPA with error: Failed to create .itmsp for 'appname' status code 401

Question

I am trying to upload an ipa to Transporter (to get new version on TestFlight) and have successfully done it in the past. However, today I tried to upload and it stopped with this error popup on the screen:

Failed to create the .itmsp for 'Appname'. The web service returned an unexpected status code (401 instead of 200)

screenshot: screenshot of error

Notes:

tried multiple times today with same issue
App is a Xamarin app thus can't upload the other way (Xcode > Archive)
using Transporter app released by Apple

@matt just tried again (so 24 hours later) and no luck – dthumma Jan 08 '20 at 18:07 — dthumma, Jan 08 '20 at 18:07

Try completely shutting down your device and then turning it back on and trying.

I had the same issue for most of yesterday and couldn't find a solution, and just now a reboot of my MacBook made it work instantly.

Worked for me. It makes me sad that this is (sometimes) the solution. – Mark B Jun 03 '20 at 08:17

Simply restarting Transporter was enough in my case – JAnton Jun 06 '20 at 21:43

Just relaunch Transporter app, or quit and r-enter it again.

I fixed my problem by matching the case of the SKU. com.company.appName wasn't accepted. I had to change it to com.Company.AppName on my info.plist.

Some times it may due to memory issue. Check your memory. Free space up to minimum 2 GB for big project

Make sure to create an entry for your app in https://appstoreconnect.apple.com ?

I am getting that issue when I left build number empty. It seems like you could face the same sort of issues if you left Identity into under General tab.

For me it was memory full issue. Freed up some space and the .ipa file was immediately accepted!
