Question

How do I enable QUIC and HTTP/3 in LiteSpeed?

Answer

QUIC is enabled by default in Litespeed. To use HTTP/3, a domain must have a valid SSL certificate, and UDP port 443 must be open in the firewall and other related security configurations. HTTP/3 connections are automatically performed when using a browser that supports HTTP/3.
