I'm on PC and I'm using Chrome, what I noticed is that the domain address changed to piti.vip from the original one pitibet.io as shown on this screenshot:
http://prntscr.com/uzws0vThere is also an information on that error page, it says that your website has banned the country/region/ip address.
So it seems that you have some countries restriction, I havent checked/read all your ToS btw.
Thanks for the free $10 but I think I wont be able to use it if it is true that you have banned some countries/region.
Same thing with me when I want to log in always Error 1009, is this really a ban on some restricted areas including our country from being unable to enter the site?
Are you another step apart from using a VPN? I think when registering it is fine but I really have trouble logging in and it seems like it's limited by a certain IP.
