App store connect 403 forbidden when saving a new build

The best way I can describe it is by showing the behavior of the website.

I am submitting a new build to the app store via app store connect. I choose a build, set the version, click save and then i get 403 forbidden (API KEY) not sure what to do from here.
The build works on testflight, and the app store connect tells me the build is ready for submission
