Přihlášení vždy až na druhý pokus

Ahoj,

řeším docela zajímavý problém. Vždy když si otevřu nově prohlížeč a chci se přihlásit do aplikace, tak se přihlásím vždy na druhý pokus (login je správný). Děje se to jen při novém otevření prohlížeče, pak už vše šlape jak má. Napadlo mě, že by to mohlo být způsobené sessions ale ta funguje okamžitě bez problému.

Já už si s tím nevím rady a ta chyba je prostě vidět.
