sites do not open

 My greetings,
I would like to implore you a favor.
On the game when I click on a button to open a website nothing happens. Whether it's the realm information button or the one to buy one. It's the same with mods that add buttons with the same purpose as Optifine; when I click on the button change its cape, nothing happens. I beg you to help me because it disturbs me for a moment. Thanks to all the team for the work provided. You are the best.
