iPhone Sign Out Issue

I am logging in to this site using mobile phone ( iPhone 4S - iOS 8.2 - Safari ) . After browsing a few pages it signs me out. Anyone having a similar issue ?

Is it site or phone setting releated ?

@Afternova  tried but it did not help. I have logged in, browsed to Client Lounge and to following topic ;

then it said there has been an issue with the site and it is reloading which has ended with following error ;
