I try to do, but when i turn to bypass my domain A record, the protocol h2 is working. All correct in browser and apache logs.

When i turn on the cloudflare on the domain, the browser is working fine(I know the CF is working on HTTP2 protocol with the clients).

But I saw these in the apache logs: “GET / HTTP/1.1” 302 5067 "GET /en/ HTTP/1.1" 200 5068 "POST /en/ajax/user HTTP/1.1" 200 77

It's using http/1.1, but I don't know why.

I try to force http2 protocol, but no difference.

Any idea ?:slightly_smiling_face:

Thank you!

You can use HTTP/2 to origin as of June 14th, 2022:

1.  Log into the [Cloudflare dashboard](https://dash.cloudflare.com/login) and select your account.
2.  Choose the domain that will use HTTP/2 to Origin.
3.  Click **Network**.
4.  Under **HTTP/2 to Origin** set the toggle to On.
