Dear Plesk Team,

According to the changelog for Plesk Obsidian 18.0.71 (released on 8 July 2025), it should now be possible to enable or disable HTTP/3 on a per-domain basis via a checkbox located on the domain’s “Apache & nginx” settings page.

“The ‘HTTP/3 support’ checkbox can be found on any domain’s ‘Apache & nginx’ page.”

After updating to this version, I am unable to find the mentioned checkbox on any of my domains.

I have already verified that:
  • HTTP/3 is enabled at the server level (verified in nginx config)
  • The domains are correctly configured and accessible
  • Caching is cleared and the interface reloaded
I’ve attached a screenshot of the expected settings page where the checkbox should appear.

Could you please clarify whether this might be a bug or if there are additional requirements or conditions that must be met for the HTTP/3 checkbox to be visible?

Thank you in advance for your support!

Best regards,
 
Ja, ich verwende Nginx und habe den Browser-Cache geleert. Ich habe auch das Ignition-Konto verwendet, aber ich sehe immer noch nichts.
