Some users got the same notifications when the Betfury site was not working correctly during the recent DDoS attack. So I assume you can't access the site because the Betfury team probably banned some ranges of IP addresses, not your account. By the way, if you use a VPN service to access the Betfury site, the problem could be because of this. In that case, you should try to change it to another one.
I have had the exact same issues when accessing them using a VPN service. Changed VPN and now I don't have any problems anymore to access the site.
@toptort, congrats with leveling up! Are the daily tasks really interesting? I always thought the rewards were quite low for the requirements you needed to fullfill.
