    Hi, please add the app.UseHangfireDashboard("/hangfire"); middleware before the app.UseConfiguredEndpoints(); middleware:

    public override void OnApplicationInitialization(ApplicationInitializationContext context)
{
    //...
    app.UseHangfireDashboard("/hangfire"); //should defined before UseConfiguredEndpoints()
    app.UseConfiguredEndpoints();
}

    Then, you should be able to see the /hangfire page:

    Thanks - that solved the problem.

    I had been following this page of documentation:

    https://docs.abp.io/en/abp/latest/Background-Jobs-Hangfire

    I'd say it should be updated to add this requirement.
