Question about QUIC, enabling, settings, etc

[jkdove]

So when I test my own server,

https://seo-lagniappe.com

(I'm on a VPS with A2hosting.com) I receive the h2 protocol response in Chrome DevTools.
My header response is:

alt-svc: quic=":443"; ma=2592000; v="35,37"

I'm using Let'sEncrypt for my SSL/TSL

When I look at other Litespeed servers, including this very site, I see "http/2+quic/39". The header response for this site is:

alt-svc: quic=":443"; ma=2592000; v="35,37,38,39"

I'm running LiteSpeed Web Server Enterprise 5.2.6 and in my Tuning configuration, it says:
A list of enabled QUIC versions. Supported versions are Q035 and Q037, other values will be ignored.


So I'm wondering ... why are my settings and responses so different from other LS servers (on the same host) as well as Litespeedtech.com's?

I've been through the entire Knowledge Base, I've been through the Wiki, I've read the configuration instructions .. nothing seems to help or explain anything that answers my questions.

Please help.

Our current latest version (5.2.6 build 2) should support v="35,37,38,39".
Please do a forced upgrade to see if it helps.

/usr/local/lsws/admin/misc/lsup.sh -f -v 5.2.6

If the problem persists, you can log a ticket with us with tmp root ssh access to your server for us to take a look.

Also, ensure to leave "QUIC Versions" setting to "not set"/blank, which is system default setting. Normally the supported version should not be manually changed. All supported version will be enabled automatically by default and you should see them in header automatically.

root@server:misc]$ lsup.sh -f -v 5.2.6                                                                   
-bash: lsup.sh: command not found

So while that command did not work, by setting "NOT SET" in the Litespeed WebConfig, I can now see this in the Response Headers:

alt-svc:
quic=":443"; ma=2592000; v="35,37,38,39"

So while that command did not work

that command does exist.
run either

 /usr/local/lsws/admin/misc/lsup.sh -f -v 5.2.7

or in your case,

./lsup.sh -f -v 5.2.7

-bash: lsup.sh: command not found

will disappear.
