No accounts with iTunes Connect access have been found for the team

Solution 1:

• Quit Xcode completely and re-open it to resolve the problem.

Solution 2:

• Please verify if it's App Store distribution profile or not.
• If yes then try to login to Xcode with your apple Id which has access to iTunes Connect or App Store Connect.
• While validating the archive file please choose the same profile. It should work fine.

When this happens to me, closing Xcode completely and re-opening it solves the problem.

Ran into this problem just now. Complete shutdown and restart of Xcode did the trick for me.

Just restart Xcode and it will work :)

Definitely it will work in Xcode 9 alternate you can try with Application Loader.
