Error opera GX games mobile

Hello, I just uploaded my first game to gx.games, this game is for mobile;
It uses encrypted text which is a json to save a loading system, it only works on PC and Android, it even works in Opera on PC.
and I test it on all browsers, for PC and mobile, I mean it works fine on all platforms except mobile in Opera browser :S
(it's a bit ironic) I get this error:

Does anyone know what's going on?
Thanks
