HTTP/2 greyed out

Hi @VDM, once you try the site @sdayman mentioned, let us know if you see HTTP/2. You can also try curl -svo /dev/null https://example.com to see if you get < HTTP/2 200 in the reply. The best suggestion I’ve seen is to try via the API, Cloudflare API v4 Documentation. HTTP/2 is enabled for all zones but not available to disable via the UI on some zones (I cannot on my free zone, but can on business and enterprise).
