I have a problem at my Login page where IdentityHelper.SignIn fails to authenticate every now and then.
It works fine locally, but when accessed through the Internet, it fails most of the time. Sometimes it works for a few minutes after I restart the IIS. I tried two different machines and end up the same.
I have googled this and did not find any answer. The only thing I can think of is the slow upload connection speed. It's 0.78 Mbps.

IdentityHelper.SignIn fails to authenticate

Hi guys,
I have a problem at my Login page where IdentityHelper.SignIn fails to authenticate every now and then.
It works fine locally, but when accessed through the Internet, it fails most of the time. Sometimes it works for a few minutes after I restart the IIS. I tried two different machines and end up the same.
I have googled this and did not find any answer. The only thing I can think of is the slow upload connection speed. It's 0.78 Mbps.
Has anyone had the same issue before?
Thank you guys!

Hi suencien,
According to your description, we can’t find the reason caused this issue.
Could you please post more about error message?
Do you use windows authentication or forms authentication?
Besides, I suggest you could check the IIS log file to find the reason.
More details, you could refer to follow link:

I Brando,
Thank you for your response. Sorry for replying late :)
There are no error messages. User.Identity.IsAuthenticated will just return false despites the right user name and password.
Sometimes, authentication works for a while after we restart the IIS.
UserManager manager = new UserManager();
ApplicationUser user = manager.Find(txtUserName.Text.ToLower(), txtPassword.Text);
IdentityHelper.SignIn(manager, user, cbxRememberMe.Checked);
IdentityHelper.RedirectToReturnUrl(Request.QueryString["ReturnUrl"], Response);
Nor
IAuthenticationManager authenticationManager = HttpContext.Current.GetOwinContext().Authentication;
System.Security.Claims.ClaimsIdentity userIdentity = manager.CreateIdentity(user, DefaultAuthenticationTypes.ApplicationCookie);
authenticationManager.SignIn(new AuthenticationProperties() { IsPersistent = cbxRememberMe.Checked }, userIdentity);
Same results.
When the site is accessed locally, the authentication problem happens a lot less.
Any ideas mate?

Hi suencien,
Since this issue is no error messages and sometimes works well, I suggest you could use Visual Studio to check your codes to make sure it has value.
I suggest you could set a breakpoint at this line to check the user has value, firstly.
Are all your user name lowercase?
Best Regards,
Brando
