I have never faced with those browser problems and also never heard people faced it before. There are two reasons why people use vpn to visit the site, first because of their internet connection is to slow/poor and the second thing is the site has a possibility of banning IP address from some country. But I am pretty sure that windice do not do it (ban IP address).
Using
VPS to play on gambling sites, are you serious about this? I have followed the Windice topic for months, and played on the site in the same period, honestly I have not had connection issues with them. The site operates fast and smooth, besides its good supports from their mods in chat box, in which I almost can ask for help anything with nearly real-time responses, not only from their mods but also from kind-hearted chatters. Additionally, their sites allows dicers to instantly withdraw their money with minimum limit at 0.002
BTCVPS is a virtual private server and there is no reason to use it to play on a gambling site indeed
think you confused it with VPN which is a common thing to add some privacy to your online activities , mind you , only some
many gamblers use VPN and it is normal , but in this case the speed of your connection is lower and the quality is lower too
so if your connection is slow, try to disable your VPN and check the speed , if it is ok , then it is your VPN
windice doesn't ban IP , there is no reason to be doing it , just because it can be easily changed with the said vpn service if need be
