Cannot connect some website via Wifi

Boa tarde @JIAWEI HU,

Acabei de testar e tenho aos 3 site que refere.

Por favor informe qual é o nome do seu serviço de internet fixo.

Uma possibilidade é o IP address que obteve estar blacklisted, por vários motivos, sendo o mais provável pela prática de CGNAT pela NOS.

Obrigado

Thank you for your quick response.

 @Jorge C 

I can not understand “nome do seu serviço de internet fixo” .  My public ip address?

I mean the name of your service.

Translate documents & websites | Google

Thank you

@Jorge C 

I don’t provide any service . I just visit website Youtube\google\twitter… via Wifi.

I mean the internet service name you are paying to the ISP NOS.

Thank you

Sorry, this question really stumps me. Can you give me an example of “Internet service name”? Or where can I find my Internet Service Name?

Muito obrigado！

Please check the internet service you are paying following this steps.

Thank you

The NOS app and the website are both changed ， only show the mobile phone information：

from my bill last month， it shows：

I have tried my best to show all the information ， sorry.

The problem happens when accessing via mobile data or the residential service?

Thank you

This problem happens just via my home wifi . 

I can visit these websites via my mobile data.

This morning , I went to NOS loja , I can also visit these websites via FreeWifi provided by NOS loja. 😂
