Im refering to the I.P. of your Friend sir... coz in some cases... some I.P.s here in the Ph is Static...
from the internet:
Is 4G a dynamic IP?
The IP address is dynamic. It changes every time you get disconnected and reconnect. The connection also gets reset automatically every once in a while as the length of a single session is limited. Once the session ends and the new one starts, your IP may change.
from the activities we can see every week in our community.... lots of teams come and go and some show patterns of being a repeated offender.. it is not impossible that... the IP your friend used was listed in the blocked list... I once encountered a login error some time ago so I did chat to one of the BB... and he said that... They do block I.P.s... Good that our ISP that fay was the one guilty for me not being able to access the site.
Congrats to you then sir... If what you said was true... Enjoy...
