Hello!

No, we didn't ban all of Indonesia.
That would cut off like, 99% of our players.

Anyway, if you are having trouble logging in using the same PC you have been using for a long time,
It is likely due to a cycling IP address.
In some areas, ISPs will cycle IP addresses.
So, it may have just so happened that your IP randomly landed on an IP that was blocked some time in the past.
Honestly, this happens kind of often.

Give it a day or so, and if you still can't log in, send us a ticket.
