Добавление QUIC в PeerTube повышение стабильности соединения

Hello everyone, QUIC gives stability, with an unstable connection of mobile devices, this has been tested on many applications repeatedly. Since I am concerned about client errors, and video freezes when using mobile devices, let’s watch together (test) videos with HTTP 3. Test version of the server PeerTube I will leave it for testing for a while
Enable in the browser
Iceraven, firefox
To enable HTTP/3, type about:config into the browser string and find
network.http.http3.enable
network.http.http3.enable_0rtt
network.http.http3.enable_kyber

Making them true

For Brave, just type chrome://flags/#enable-quic into the browser bar and select enable
After that, restart the browser.

  1. Update Nginx to the latest stable version
  2. Add the QUIC Settings

Hello everyone, I’ll leave it here, QUIC will only work fine if you open UDP port 443, otherwise there will be no connection

ufw allow 443/udp #Для QUIC

I also created a file called http2-directive.conf and put it in etc/nginx/conf.d with the contents according to the official documentation.

http2 on;

Also for relay protection

  # TLS 1.3 0-RTT anti-replay
  if ($anti_replay = 307) { return 307 https://$host$request_uri; }
  if ($anti_replay = 425) { return 425; }

Place the file 0rtt-anti-replay.conf with the following contents in /etc/nginx/conf.d

# Implement TLS 1.3 0-RTT anti-replay for NGINX

# Requires: NGINX directive "ssl_early_data" on

# Usage:

# Make sure these "map" blocks are included in "http" block
# Put the following two lines in SSL "server" block, before any "location" blocks

# if ($anti_replay = 307) { return 307 https://$host$request_uri; }
# if ($anti_replay = 425) { return 425; }

# Pass "Early-Data" header to backend/upstream
# Only for 0-RTT requests from clients that understand 425 status code (RFC 8470)

# fastcgi_param HTTP_EARLY_DATA $rfc_early_data if_not_empty;
# proxy_set_header Early-Data $rfc_early_data;

map "$request_method:$is_args" $ar_idempotent {
	default 0;
	"~^GET:$|^(HEAD|OPTIONS|TRACE):\?*$" 1;
}

map $http_user_agent $ar_support_425 {
	default 0;
	"~Firefox/((58|59)|([6-9]\d)|([1-9]\d{2,}))\.\d+" 1;
}

map "$ssl_early_data:$ar_idempotent:$ar_support_425" $anti_replay {
	1:0:0 307;
	1:0:1 425;
}

map "$ssl_early_data:$ar_support_425" $rfc_early_data {
	1:1 1;
}

As a result, we get a config for Ngnix version no lower than 1.25 (check nginx -V to ensure there is an with-http_v3_module)
