Thank you !

Please , can you check again? I’ve got still this error. I was try change ssl to flexible but website was dead. Now i’m again use full ssl and stil got this error.

Yes but we spoke about www.darkmodders.pl or darkmodders.pl
Problem is only on mobile devices. On computer everything is okey.

I dont know, i just tried it on PC and mobile. Working fine for me. Imgur

Strange for my. My friend has also this error on their mobile phones. But thank you much for help !

Probably your SSL is signed by an intermediate (with is the normal way) and Android cannot handle that.
