QUIC request with google chrome

Question

I am trying to force Google Chrome to use QUIC as the underlying protocol instead of TCP.

I used this command to force QUIC through the command line, but it doesn't work:

chrome --disable-setuid-sandbox --enable-quic --origin-to-force-quic-on=IP:443 http://IP:443/

Wireshark shows me that Google Chrome is still using TCP for that destination.

BTW i am using google chrome Version 97.0.4692.71

Can anyone help me in that matter.

Answer 1

just trying to find a solution for chrome to use http3 without forcing it to, does not work for my local nginx-quic setup, firefox works out of the box... Just found your question. If i remember correctly you can only pass a single domain with that flag to chrome. This works for me:

--origin-to-force-quic-on=mylocaldomain.local:443
