Resolved HTTP2 already enabled, Apache still using 1.0 in few requests

Hello,

HTTP/2 is already activated, however, I notice in the LOG requests that go through HTTP/1.

I checked on this site (HTTP/2 Test - Verify HTTP/2 Support | KeyCDN Tools) and the output is as follows:

HTTP/2 protocol is supported.
ALPN extension is supported.

Another information: I use the proxy mode.

Any idea why this happens?

I guess what you are seeing are HTTP/1.0 requests in the Apache log files (access_ssl_log). That's normal: nginx is the frontend server which is supporting HTTP/2 (as confirmed by your tests) but is using HTTP/1.0 internally to proxy the connection to Apache.

So short version: Nothing to worry about, it's expected behaviour.
