When I try to inter mirai.io it gives me these massage Checkingyour browser before accessing mirai.io It tells me to wait for 5 sec but it keep repeating the 5 sec while in chrome after 5 sec I enter mirai.io can u help?

That is from the website or something between the site and you.

I had the same problem. But when I reloaded the page, using <shift> F5, it then loaded.
