Asp.NET Identity stopped working on Chrome -

for unknown reason, no longer can log in own application on chrome.

this how i'm doing signing in:

    [allowanonymous]     [httppost]     public async task<actionresult> login(loginmodel model)     {         if (user.identity.isauthenticated)             return redirecttoaction("index", "home");          if (!modelstate.isvalid)             return view();          var status = await signinmanager.passwordsigninasync(model.login, model.password, true, false);         switch (status)         {             case microsoft.aspnet.identity.owin.signinstatus.success:                 {                     int userid = user.identity.getuserid<int>();                     if (usermanager.isfirstlogin(userid))                     {                         return redirecttoaction("declaration", "home", new { returnurl = model.returnurl });                     }                      return redirecttolocal(model.returnurl);                 }             default:                 return view();         }     } 

i debugged code , passwordsigninasync succeeds, chrome shows no cookies set page. in effect redirection action, marked [authorize] attribute redirects again login page.

i tested site on ie , works correctly, can log in , out , cookie being set correctly.

if can provide more detailed information, tell me.

edit: more details

i've been testing piece of application, date-time sensitive (stops displaying after specific date). changed system time 01 august 2016, logged in , switched now. when stopped working.

what curious, when switch future time, can log in again , session cookie being set correctly. when return "now", can not log in again.
