Alt-svc onion header is never sent

Are you still seeing this issue? I’ve just checked my own domains, and I see the alt-svc header in Tor browser. (Copying the request to cURL does not display the header)

yes this is the alt-svc I get with latest Tor browser, browsing to https://www.highcanfly.club :

alt-svc: h3=":443"; ma=86400, h3-29=":443"; ma=86400

Do you have Onion Routing enabled in the Network tab?

Yes !


I just tested it with my own zones, and I’m having issues too. On the first zone I only get the Alt-Svc (with onion routing address) header on certain subdomains, while on the second zone I get it on the apex too :thinking:

I am actually getting the header on your domain. I requested a new TOR circuit and it works on my apex domain too now. Could you see if that fixes the issue for you too? That definitely shouldn’t be necessary, but I cannot say what might be the cause.

No same if I request a new Tor circuit !


Tor browser is latest:
