ASP.NET Forms Authentication – Too many redirects

I have an ASP.NET 4.5 webforms site and trying to setup forms authentication. I have an Account folder with a Login.aspx page within. The main web.config contains the following:

<authentication mode="Forms">
  <forms loginUrl="~/Account/Login.aspx" timeout="2880"/>
</authentication>
<authorization>
  <deny users ="?" />
  <allow users = "*" />
</authorization>

When I browse to the site, it appropriate redirects to Account/Login.aspx and then throws a browser error indicating

Too Many Redirects

. I am at a loss as to what could be wrong or where to go to troubleshoot next. Any assistance would be appreciated.

Method 1

Please check if you have somewhere on your page that you have redirected to same page that you are in, or somewhere global, this endless loop.
eg Response.Redirect("Login.aspx");

Method 2

I have seen this before and the issue was resolved by clearing cookies and browser history.

Method 3

Check that your ASP .net State Service is running. Starting this service resolved this problem for me.

Method 4

Having an older version of the .Net Framework Runtime than is used by the application would also be the cause of this type of error.
