Nuget resource change from https to http

I try to upload a NuGet package but a receive this error:

An error was encountered when fetching 'PUT http://nuget_domain/api/v2/package/'. The request will now be retried.

But in the https://nuget_domain/v3/index.json is 'https://nuget_domain/api/v2/package'

Y want to know why it tries with http with it is configurated with https and how to fixed.

Regards
