Yeah, something went wrong with my DNS server.I'm still getting "504 Gateway Time-out"
If I try to use HTTPS then I get "503 Service UnavailableBash:> curl -v http://nextcloud.pineappledude.ru/index.php/s/FMinZywaoqTJfEJ * Trying 195.91.170.231:80... * Connected to nextcloud.pineappledude.ru (195.91.170.231) port 80 (#0) > GET /index.php/s/FMinZywaoqTJfEJ HTTP/1.1 > Host: nextcloud.pineappledude.ru > User-Agent: curl/7.79.1 > Accept: */* > * Mark bundle as not supporting multiuse * HTTP 1.0, assume close after body < HTTP/1.0 504 Gateway Time-out < cache-control: no-cache < content-type: text/html < <html><body><h1>504 Gateway Time-out</h1> The server didn't respond in time. </body></html> * Closing connection 0

Now it's available.
