Uploading IPA to apple with altool not working

Question

So I'm trying to upload my ipa to apple. but this stopped working...

xcrun altool --upload-app -f ./dist/myapp.ipa -t ios --apiKey "KEY_HERE" --apiIssuer "ISSUER_HERE"

I'm getting:

Request ID: FTP34GRCKE5NK6HNMWTJXEN7.0.0
2019-10-22 10:39:33.371 altool[72993:10589325] *** Error: Errors uploading './dist/myapp.ipa': (

But when I log into iTunes connect the key is still valid. I have no idea why this isn't working any longer. I thought it might be the Key, but I made a new one and still get the same error.

xcrun version 48.
Xcode version Version 11.1 (11A1027)

Answer 1

The error Authentication failed typically hints that you have provide wrong credentials.

What did you use for --apiIssuer "Issuer_Here"?

• Don't use a mail address for "Issuer_Here"
• You can find the issuer ID on https://itunesconnect.apple.com/access/api (top part of the page, below sections People/keys)
