Unable to Download API Key

As an admin I am trying to download API Key created by account holder. I see download button. I press it. And file is not downloaded. It just redirects me to - https://appstoreconnect.apple.com and that's it. We tried to recreate key, to use different admin accounts, to clear all cookies, use private safari browsing. And we were still not able to download it. Here is the log from Safari right after download button is pressed:
