Latest build failing in AppVeyor - API key issue

[boflynn]

From the latest build:

Successfully created package 'C:\projects\system-net-mail-abstractions\System.Net.Mail.Abstractions\build-symbol-package\System.Net.Mail.Abstractions.1.1.21.symbols.nupkg'.

info : Pushing System.Net.Mail.Abstractions.1.1.21.nupkg to 'https://www.nuget.org/api/v2/package'...
info :   PUT https://www.nuget.org/api/v2/package/
info :   Forbidden https://www.nuget.org/api/v2/package/ 229ms

error: Response status code does not indicate success: 403 (The specified API key is invalid, has expired,
    or does not have permission to access the specified package.).

Does the project need to have its AppVeyor key refreshed?

Thanks, I swapped to using github actions to generate the nuget package.
Version 1.1.21 is available now on nuget.org
