@DigiVoyager The account was created while I was in Japan.
A mobile with Jazz sim can be logged in, as well as browser on my laptop.
(not sure if once I would log out, it would allow me to login again tho)
The problem occuring is only another mobile w/o Pakistani sim (cause this one is for my JP sim) via only Wi-fi. It can't be logged in since last week. 🙄
Your Zong's communication behavior also seems something strange in other way though...🤔
@browneyes Yes, it seems to be some sort of oddity, but many Zong 4G IPs have been used by botnets, hence the problem. Though I am not sure about the tunnel redirection.
And indeed, logging out and then logging in via the new IP is the big test. But don't do it, that is how I lost many accounts. In your case the Wi-Fi's IP address must be an issue.
