Samsung android tablet problem

I have 2 Samsung tablets. Suddenly i am unable to reach the site with one of them. I need to solve this problem because, it is my traveling device. Things are ok with a Samsung A1. The problem tablet is Samsung is galaxy s2. I appreciate any help.

Hi Lusan,
I am sorry to hear that. Do you get any error message when you try to access the site? Which browser are you using and does it help if you try another browser?
