I'll investigate it later if no one comes with an answer ahead of me.

alright thanks 🙂 rn it seems to be on http2, also good but http3 is ofc better

It does not look that promising. Traefik does not have port 443 bound to udp, only tcp. it's possible to change it and spin it up again, but that will probably be overwritten with updates

hmm sounds scary should i maybe add a gh issue to add offical support? (to the dokploy gh)

Henrik•3mo ago

There is one that was closed. I have already left a comment on that one. Maybe it's a good idea to create a new one, but we can also wait a bit and see if they open the old one again

Attacler/BartOP•3mo ago

sure! Can you link it to me so that i can folloe it?

I found a solution which survices restarts

Henrik•3mo ago

I was wrong. It does not work after full reboot 😦

Attacler/BartOP•3mo ago

hmm too bad hope that someone will have a solution that can be baked into dokploy itself

Henrik•3mo ago

I am writing a PR as we speak I have written my own script which enables it on reboot tho

Attacler/BartOP•3mo ago

nice and thank you!

Sorry to use this thread, but Dokploy version 0.20.0 came out today and it has http/3 integration. Does anyone know how to activate http/3? I can't find anywhere how to do it.

You need to make a slight change to traefik.yml file

entryPoints:
  web:
    address: ':80'
  websecure:
    http3: {} # Add this
    address: ':443'
    http:
      tls:
        certResolver: letsencrypt

entryPoints:
  web:
    address: ':80'
  websecure:
    http3: {} # Add this
    address: ':443'
    http:
      tls:
        certResolver: letsencrypt

That's it And open up udp on port 443 on your cloud provider if you're using any firewall

Thank you so much, it works 🙂

Attacler/BartOP•2mo ago

seems like this has been rolled out as an official version 🙂

Henrik•2mo ago

They mentioned in the release notes how to fix it. But it will only be on by default on new installations

Attacler/BartOP•2mo ago

jup, i saw that altho i did edit my traefik config (and reloaded it) and allowed the udp port in my firewall, it doesnt appear to use http3 👀 any pointers?

Henrik•2mo ago

Sometimes your browser just doesn't care. Check here with your domain to see if it worked. If it says that's good, your browser may want to use it if it wants to

HTTP/3 Check

Is my site using HTTP3? Check HTTP3 service on any URL. Test QUIC service, too.

Attacler/BartOP•2mo ago

your right 🙂 thanks!

Henrik•2mo ago

So it worked?

Attacler/BartOP•2mo ago

jup! but my browser was indeed not picking it up, restarting chrome did the trick

Fakerko•2mo ago

For me works load website few times with cache disabled. Then I saw h3 in dev console.

The site for me says that HTTP/3 is supported, but in the HTTP Header just below, the response is coming from HTTP/1.1—is that normal?
