We can’t connect to the server
Website is btcpay331939.Indyn.com but none of my browsers cannot access it, but gyazo shows it is valid. https://gyazo.com/02479dfad0ae17e2fd8c8a48a7171231 Two other people I communicate at Telegram can reach the website. How come I cannot?
First, not a firefox problem. Second the site you mentioned indeed doesn't exists in dns records. Maybe it got deleted after screenshot you mentioned was taken.
indyn.com works, but offers the domain for sale.
