Unable to sign in to AMO – “You do not have permission to perform this action."

Hello Mozilla Add-ons Team,

I am unable to sign in to the Firefox Add-ons (AMO) website with my Mozilla account.

Mozilla Account email:
s2nguyenhoaianh@gmail.com

I can successfully sign in to my Mozilla Account at accounts.firefox.com. However, when I click “Sign in” on addons.mozilla.org, I am redirected to the AMO authentication callback and receive this error:

“You do not have permission to perform this action.”

The failed request is:

/api/auth/authenticate-callback/

AMO request ID:
7239596f852d4866bd622baab8eacd39

This happens every time I try to sign in to AMO/Developer Hub.

Could you please check whether there is any restriction, suspension, permission problem, or account provisioning issue associated with my Mozilla account?

I would appreciate it if you could check the AMO account status and restore the necessary access if possible.

I have attached a screenshot showing the error.

Thank you for your help.

Best regards,
