OLS QUIC and HTTP/3

[nfn]

Hi

I'm using OLS 1.6.4 and when testing my site at https://www.http3check.net/ I get QUIC and HTTP/3 enabled.
When using Chrome should see a response protocol http/2+quic/46 but it only shows h2.

I'm using OLS 1.6.4 and have both TCP/UDP 443 ports open (in/out)

I tested openlitespeed.org and I get H3-23 Q039 Q043 Q046
Testing my site I get 0-RTT H3-Q039 H3-Q043 H3-Q046 H3-23 H3-24 Q039 Q043 Q046

Thanks

make sure your Chrome QUIC version and your local UDP 443

some ISP might block UDP traffic as well

I'm using Chrome 79.0.3945.88 and when I visit openlitespeed.org I get http/2+quic/46 protocol, but visiting my site I get h2!
I disabled all firewall rules before the test.

What Browser have you used?

Thanks for your help. Cleaning browser cache and flushing socket pool solved the problem.
