    ​@jakekiser Does the server token file you are trying to upload have a .p7m extension?

    Have you tried downloading another token file?

    I have tried multiple times. I even tried a new PEM file.

    Are you using a Mac and Safari? I believe I encountered  this issue before when I was using a Windows computer and switching to a Mac resolved the issue.

    PI-433 (PI149000) Automated Device Enrollment server tokens cannot be successfully uploaded to Jamf Pro when using the Chrome browser. Workaround: Use the Safari or Firefox browser.

    It worked for me yesterday in Safari.
