I have trouble using Wolf.bet since my IP or maybe where I live is not allowed in Wolf.bet and I can't see their terms and condition if using a VPN is allowed or not. If I use a VPN would I be able to access your site or will be banned if I insist?
I can tell you that VPN is not a reason to not be able to play. I do not know if it is allowed or not but I have been using it so far and nobody warned me about it and it didn't blocked me from gambling on it neither. So that should not be the problem.
Maybe the VPN you are using redirects to a nation that is banned to play here? Or maybe you could be using different browsers, like edge always gave me trouble with most casinos, and firefox always becomes slow after an hour of gambling, chrome always uses too much ram when I keep gambling as well, opera is the only one that is perfect for me. So, maybe it's about that? Plus, mobile versus PC matters in this situation as well.
The only way to find out if vpn is allowed or not is to ask the representative directly. It's either you pm them here, email them, or ask questions on their costumer support. That must be done before taking any risk so that we are sure that our balance and future winnings are going to be safe.
When it comes to browsers I have tried microsoft edge and I haven't experienced any problem but for firefox, it's normal that you will experience a slowdown because this browser consumes much ram. It was the chrome actually that uses less ram but there are lighter browsers available like opera which he can try and see if that can solve the issue.
