Hi SJ - OK, it just now let me in. Yes, I have been using a VPN for years. Yesterday, when I tried to open this website instead an Imunify360 website opened up and it asked me to solve one of those 'you are not a robot' puzzles. Despite solving the problem multiple times, it would not let me get past their Imunify360 screen.
Pretty much all hacking is done via vpn. If the vpn you are using was flagged, or an ip associated with it flagged, this kind of thing can happen. Switch your vpn server to a different city, sometimes that helps or just renew the ip.
