My website running with hangfire on the same server.
The hangfire dashboard runs well on local. However, while I access http://localhost/hangfire/recurring on the server computer, it reports this error:
Unable to refresh the statistics: the server responded with 500 (Internal Server Error). Try reloading the page manually, or wait for automatic reload that will happen in a minute.
I found out the problem on Chrome DevTools: The http://localhost/hangfire/stats returns a 500 (Internal Server Error).
Soon I found the logs about this:

I have added these code in each public async Task Invoke(HttpContext context) of the middleware to prevent it block the hangfire but the problem still here:
if (context.Request.Host.Host.ToLower() == "localhost")
{
await _next.Invoke(context);
return;
}
How can I solve this? Thank you.
Add this in startup.cs:
app.UseHangfireDashboard("/hangfire", new DashboardOptions
{
Authorization = new[] {new HangfireAuthFilter()},
IgnoreAntiforgeryToken = true // <--This
});
And now it works.
