I’m not sure what this is, but I hope it’s just a temporary error 
I don’t have active vpns on my computer.
// edit: right now, is working
That’s odd, let me send you a DM so we can take a closer look at this together 
Are you using a country-specific VPN, or changed internet providers?..
The website may restrict access from foreign countries (based on your IP address) e.g. USA
If so, turn off your VPN so your IP address is a UK server.
If your internet provider is using USA servers, ask them for a UK IP address, or conversely use a VPN and set the country to UK.
I didn’t use vpn. But after a few minutes, the site is working. Maybe it was something with my internet provider… maybe my IP changed at the same time (Eastern Europe).
I sent the details to Momchil to investigate. Thx
