Answer by MikelThief for How can I publish Hangfire Dashboard for a custom web page?

As you asked in comments comments, if you want to set up public access to your dashboard without app running at localhost, you need to add custom DashboardAuthorizationFilter which will always return true (authorize anybody to gain access).

To do this create your filter as follows:

using Hangfire.Dashboard;

namespace your.app.namespace
{
    public class PassThroughDashboardAuthorizationFilter : IDashboardAuthorizationFilter
    {
        /// <inheritdoc />
        public bool Authorize(DashboardContext context) => true;
    }
}

and then add it to your configuration:

        app.UseHangfireDashboard(options: new DashboardOptions
        {
            Authorization = new List<IDashboardAuthorizationFilter>(){ new PassThroughDashboardAuthorizationFilter() },
            IsReadOnlyFunc = context => false // according to your needs
        });
