HTTP/3 Support

[ferlu...@gmail.com]

I am using cloudflare and litespeed, checked this guide https://docs.litespeedtech.com/cp/cpanel/quic-http3/ 

I enabled http/3 on Cloudflare and my page on https://http3check.net/ shows:

when I check on the network tab it shows h2 and not h3 like in for example 

Anyone has an idea of what maybe going on?

I am using the latest OLS version on debian 10

Thanks in advance

if you have cloudflare in front , that's CF that controls/manages the connection to your browser, not OLS 

not sure what version of your FF supports , but you need make sure the H3 FF supports and CF provides , matches.

Sorry but what does FF stands for? 

I just tried disabling the cloudflare proxy 

and the check now displays:

and this is what the network tap shows now:

and something interesting is that I see than in the headers this is what I see

Basically sayting the versions that is supporting but It stills shows h2 on most requests, I wonder why?

oops , sorry ,  misread FireFox somewhere.

you can go to chrome://net-export/  to enable chrome log , see what it was doing  and it will also show the version it supports 

if your browser has failed connection before ,  try clean up browser cache and restart it few times , so it will clean up the broken history to re-try the H3/QUIC connection

Yeah, clearing up cache and site data fixed the issue. Thanks!

I've kept investigating but I can only get it working without the cloudflare's proxy. Is there a way to use cloudflare proxy && get http3?

This is the same page in a subdomain without the  CF proxy:

This is the page on a domain that has the CF proxy:

Both hosted on the same machine. Any ideas?

yeah but you should contact CloudFlare support for this, since it's CF that does the final connection to your browser, instead of OLS.
