Access Denied when updating existing Netlify Drop project despite 115 credits remaining

I am trying to update my existing Netlify Drop project bpullman-swarm.

The current production site is live and working.

I still have 115.2 / 300 credits remaining on the Free plan, expiring 19 September 2026.

When I try to deploy an updated folder from the existing project’s Deploys page, Netlify accepts the folder and begins uploading the files, but then returns Access Denied.

I have tried both drag-and-drop and “choose a folder”, with the same result.

I am not trying to create a new project. I only want to update the existing bpullman-swarm project.

Could you please check whether my account or project has been incorrectly blocked from production deploys?
