ipv6 not working

[ddegner]

My website daviddegner.com has been up for a while but ipv6 doesn't seem to be working.

When I use https://ipv6-test.com/validate.php it says:
AAAA DNS record (working) 2600:3c03::f03c:92ff:fecd:1da8
IPv6 web server (not working) web server is unreachable : Connection refused
https://www.ssllabs.com/ssltest/analyze.html?d=daviddegner.com&latest

So my hover.com domain name points to quic.cloud DNS which includes:
AAAA daviddegner.com 2600:3c03::f03c:92ff:fecd:1da8


Using the OLS webadmin panel I looked at the Listener > Summary page:
I created 2 more listeners for ipv6



But it still doesn't appear to work. Any ideas?
Do I need to open new ports in my firewall?

I'm using an Ubuntu 20.04 install from the OLS super simple install on this website so it should be a pretty default install.

Thanks!

No extra port allowed needed, it should just work.
May I know the OLS version? and if this IPv6 interface can be found from the server?

ip addr

Thanks for looking. I just tried opening and closing ports 546/547 for fun. I left them closed for now

Hi,

I just set up a pure OLS test server and it works on both HTTP/HTTPS IPv6 validation
AAAA DNS record 2400:6180::d0:0:0:f8a:3001
IPv6 web server LiteSpeed

Only need to set "[ANY] IPv6" on port 80 and 443 listeners. No need to set multiple port 80 and port 443 listeners.

I just found out that you use quic.cloud, if you have IPv6 issue with it, then it may be not OLS related. Can you confirm if the issue still shows without any CDN service in the front?

 

[ddegner]

I restructured my listeners to be just [Any] IPv6, and that doesn't seem to work at all. I can't load any pages.


I also bypass the CDN now and moved me DNS from quic.cloud to my linode DNS. I'll wait a little bit for changes to propagate, but that doesn't seem to help.

Hmmm, yeah I think it worked perfectly when I installed it a few months ago.

Hi,
If you can reproduce/confirm something is still not working properly, in this case is IPv6, then please send a ticket to bug@litespeedtech.com so we take a further look.

I don't know how, but I got it working by playing around more with the DNS and the listeners.
