We are setting auth cookie as follows:
var authTicket = new FormsAuthenticationTicket
1, principal.Email, DateTime.Now, DateTime.Now.AddMinutes(1200),
false, JsonConvert.SerializeObject(principal), FormsAuthentication.FormsCookiePath
var enTicket = FormsAuthentication.Encrypt(authTicket);
var cookies = new HttpCookie(FormsAuthentication.FormsCookieName, enTicket)
Expires = DateTime.Now.AddMinutes(1200)
response.Cookies.Add(cookies);This cookie expires in 10 mins. Windows log viewer says:Event code: 4005 Event message: Forms authentication failed for the request. Reason: The ticket supplied was invalid. Any ideas what can happen and how to fix that?

It could be the application is restarting after 10 minutes and the machine key is configured to auto-generate which invalidates the token. Try setting a specific machine key in the web.config.
Do a Google search and you'll find plenty machine key examples.

Please change the Session timeout to 30 minutes or more and see if the changes in your forms authentication cookie behavior. u can solve your problem
