QUIC problems!

[gluktd]

How can i get the quic working on Virtual Hosts?
I see it's working on WebAdmin. The indicator is green, but on my VH which is on subdomain indicator is blue(HTTP2 only).

Shows - "QUIC connection could not be established"
Ports are opened.

For QUIC, UDP port 443 must be open for incoming && outgoing connections. If you have firewall running check if both directions are open.

Firewall is disabled.


Thank you for your reply! I'm fighthing with this thing for a long time.

What about QUIC in WebAdmin console? Is QUIC enabled?

yes it is enabled on all levels. Server-Listeners-Virtual Host. And it is working on WebAdmin Console on it's own. But doesn't work on VH, VH is runing LSAPI on lsphp74, it's showing only http2.

Please take steps as https://docs.litespeedtech.com/cp/cpanel/quic-http3/#enable-or-disable-quic to find out why. It has nothing to do with lsphp.

Check this out if you don't use any control panel software like cPanel.

Good. I know this instruction from memory. But let's walk through it together.

Must have QUIC enabled in GUI/conf - enabled on all levels.

• Must use either Chrome or Opera with QUIC enabled - enabled in all browsers ( i see quic enabled right now on this forum)
• Must not use self-signed certificates only trusted certificates will work - cert is from certbot.
  
  
• Must configure SSL Settings correctly - SSL is configured exactly like on link
  
  
• Must have UDP Port 443 open at the firewall - No firewalls is running.
  
  
• QUIC will not work with a proxy front end like CloudFlare - not using.
  
  
• QUIC will only applied to HTTPS, not HTTP - i'm using force redirect from http to https
• QUIC can be enabled at the server level, listener level or virtual host level - done.
• 
  
• QUIC won't work with LSWS 5.2.8 anymore as Chrome only speaks "quic/43", while LSWS 5.2.8 only supports up to "quic/39" - LSWS 5.4.8 is installed
  
  
• By the way...
  1. No control panels is used.
  2. Bad cache certs is impossible, because different browsers and tonns of wiped browser cache.
  3. CSF is not installed.
