Have been breaking head on this but it isn;t getting fixed.
In chrome://net-internals/#alt-svc
For my domain I see
Code: 
https://www.dlife.in quic :443, expires 2018-09-20 02:51:23 (broken until 2018-08-21 3:1:21)
For Litespeed site also I see
Code: 
https://www.litespeedtech.com quic :443, expires 2018-09-20 02:51:02 (broken until 2018-08-22 21:17:21)
So spdy checker doesn't show QUIC
Whereas with google.com
Code: 
https://www.google.com quic :443, expires 2018-09-20 02:49:58
-- and the SPDY checker shows green.
QUIC is enabled on server.
domain has ssl
ports are open for 443 UDP

Running V 5.3
Chrome Version 68.0.3440.106 (Official Build) (64-bit)
cPanel/CloudLinux setup

Any clue?

Sometimes browser does not establish quic connection at beginning, so if you refresh again, you will see the checker is green. I just checked for your site.
Your site does not have LSCache enabled which you should look into now, that's more improvement than QUIC.

Problem is that this issue is not just happening with me but everyone across different locations in India.
I have tried refresh a 100 times and yet the same issue.
I have tried this refresh on your site too. Same issue.

And whenever I access google.com it's always green. Never ever has it shown otherwise.

I have the same chrome version, my chrome got:
Code: 
https://www.litespeedtech.com quic :443, expires 2018-09-19 18:24:37
Code: 
https://www.dlife.in quic :443, expires 2018-09-19 18:21:13
QUIC for both sites are working fine.
More likely you have UDP connectivity issue.

Ok.
Now onto LSCACHE
I use WP and XF on the domain mentioned
I use a third party plugin for SSO. (XPRESS from themehouse.com)
Will LSCache work with such a setup where all Login is redirected to XF and user logs in to XF. Then when the user navigates to WP, (s)he is auto logged in there also.

If it was UDP issue, same thing should also happen on google.com. But, it never happens. It's always green.

For your lscache questions, as far as you enabled cache for both WordPress and Xenforo. It should work. Not sure your third-party plugin for SSO is compatible with LiteSpeed plugin or not. Generally, it should work. you can give it a try and let us know if there is an issue.

QUIC wont work with 5.2.8 any more as chrome only speak `quic/43` , 5.2.8 only support up to `quic/39` .
If you switch back and forth between 5.3 and 5.2.8, it will be on and off.
stick with 5.3, QUIC should work fine.

I am on 5.3
Still no luck for anyone from anywhere in India on different ISP's
Surprising everyone sees no problems with Google.com -- always green.
If it is a UDP connectivity issue, then it should happen with Google also.
Doing a
Code: 
curl -I https://www.google.com we get
Alt-Svc: quic=":443"; ma=2592000; v="44,43,39,35"
Code: 
curl -I https://www.dlife.in we get
Alt-Svc: quic=":443"; ma=2592000; v="35,39,43"
(44 missing here)

Code: 
curl -I https://www.litespeedtech.com/
Alt-Svc: quic=":443"; ma=2592000; v="35,39,43,44"
Also, the order is reverse in case of Google - highest to lowest.

The order does not matter.
Is QUIC/43 used for google.com?
Maybe google.com was white listed for UDP.
I have no problem with your site, indicator turns green on the second access as expected.
Does chrome://net-internals/#alt-svc
still list it as broken?
You may have to use wire shark to capture the traffic while using incognito mode access the site.

LSCACHE is activated.
I find that SSO using XPRESS stops working.
A fresh login to XF
Click home and it takes to WP and asks to login again. Clickng two links (any) on WP shows logged in.
Then going to forum (XF) shows WP CSS so everything appears broken. Clicking any link gets the XF css back.
I can provide login details over PM to check.
