Thank you Wolstech for you quick response, I will try to connect with them because the domain is paid. I don't understand why they treat their customers like this. I hope to fix it.
In the other hand, i am connecting ok to Heliohost.org in my phone when not using wifi, but i can´t conect in pc or phone with the wifi. It is only happing me with Heliohost that i know. My brother live in my city and he don´t have problem to connect to the web. So i am thinking it is a problem with mi router firewal?. It is rare becouse i can connect to https://helionet.org/ perfect, i don´t know, perhaps something with the certificate¿?
