Issues with installing Mods (Network error) and https://gx.me/es/signup/

Error message when trying to download any mod

Hey guys! i've been having the same issue for a while now when trying to download any mod from the GX Mod store, I tried every solution that i've seen online including turning off Extensions, trying without a profile, turning off the fireblock and antivirus and restore the browser to default settings, nothing has work so far. The browser is not blocked from any setting in my internet and i can go online in Opera, Chrome, Firefox, etc. its only when i try to download any mod or log in on the store where i have that Network error. I runned a diagnostic on my PC and said that everything is working fine but the https://gx.me/es/signup/ is not responding.
Do u know if this is something im doing wrong or its an issue with the Browser? its been happening for me for moths now and i honestly just ignored it and thought that i wasnt going to be able to install mods and thats it, but every now and then i just tried everything to make it work without any success.
