Hello Every One!
I'm a fresh migrate from Apache2 to OpenLiteSpeed. I've managed to migrate more or less well but I can't start using http/3 with quic. OLS doesn't start Quic.
I use:
Two listeners (not counting Admin one)
and a number of Virtual Hosts.
I've double checked the enabling of Quick at Server level:
Listener:
and Virtual Host:
Also I've checked UPD 443 port that it is available from VPS and to VPS:
1. I can reach google form VPS via UDP 443. That works.
2. I'm not able to reach VPS via UDP 443 from another server (but this server can reach also google via UDP). But.
But. If I use TCPDUMP at VPS side that is listen to UDP 443 and try to reach VPS via UDP 443 from another server then suddenly TCPDUMP receives packets from another server:
Then I checked the open ports:
It seems that OLS doesn't use UDP 443. It uses only UDP for the admin listener (7081 port). Also it uses only IPv6 80 and 443 ports. But works well also with IPv4.
I've checked the error.log of the server:
it contains some infor that UDP 443 failed to be open. Without any other explanations. I've tried to check the problem with DEBUG mode but nothing more were found.
So, the server is able to receive UDP 443 but no one listen to it at the server side. OLS gives an error when trying to obtain UDP 443. All the settings are On. No quick as a result. What can be wrong?
