Ah okay thats good news. Is it worth upgrading to HTTP2 on the server side for cloudflare if they are the only consumers of my VPS? They already enable HTTP/3 for clients but I'm wondering if I'm somehow bottlenecking them by not matching my server with HTTP/2 or HTTP/3.

According to their docs Cloudflare won’t connect to your origin servers with HTTP/2 or HTTP/3 anyway: https://support.cloudflare.com/hc/en-us/articles/200168076-U...

In general connections between CDNs/reverse proxies and origin servers don’t get much benefit from HTTP/2 or HTTP/3. CDNs don’t generally care about connection establishment speed or multiplexing to the origin (the main benefits of newer HTTP versions), since they can just create and maintain N long-lived connections if they want to be able to send N concurrent requests. They generally only bother with HTTP/2 to the origin if they need to support gRPC, which has some unusual connection semantics.
