I installed on one of my ubuntu servers and allowed port 9090, but when I try accessing it from chrome it gives me a warning page "You cannot (IP) right now because the website sent scrambled credentials that Google Chrome cannot process." Is this because I run a NGINX server from that box?
If it's just Chrome not trusting the certificate, you can usually override the error by clicking "details" and then continuing by clicking a link. If the override isn't there (because of HSTS or similar), you can type "thisisunsafe" into the web page to override any non-technical certificate errors (there's no input field but it'll work)
