HTTP version confusion

Hi. I'm trying to surf to a website and I think I'm running into problems with HTTP versions.

The site is taliadinapoli.com. They sell pizza. When I try to get there from my computer (Windows 10, FF 108.0.2 64 bit) I get an HTTP 511 error. In fact, all the computers in my house - my wife's Mac and our tablets - get the error.

So I assumed it had something to do with my ISP.

But then I opened a virtual machine (Windows 7, FF 108.0.2 32 bit) and went to the site and it loaded fine. So it's not my ISP; it's something else.

I opened the developer tools and looked at the headers for the initial requests. The only difference I saw was that on my PC, where I get the 511 error, the header specifies HTTP 1.1. In the virtual machine, where the site loads, the header specifies HTTP 3.

So on my PC, in FF, I changed network.http.version to 3. That didn't help: the GET is still using 1.1 and getting a 511 error.

Then I looked at FF on my VM and saw that its network.http.version was also set to 1.1. And yet it's using HTTP 3 to access the site!

What's going on? How do I get FF to use HTTP 3?

Thank you.

What does it mean when HTTP changes to HTTPS? HTTP helps web users retrieve web pages. HTTPS, or HTTP Secure, does the same but in a more secure manner. HTTPS functions so that unauthorized users cannot access information they are not supposed to have by emphasizing secure search.

Is HTTP/3 available now? While the standard is still in development, website owners and visitors can start getting support for HTTP/3 through browsers, operating systems, and other clients. Of course, there are likely more changes ahead for the standard, which has already gone through several implementations.

After HTTP/3 is released, the entire web will not switch over at once. Many sites are not even on HTTP/2 yet.

One potential hurdle for the new protocol is that it requires increased CPU usage for both the server and client. This will likely decrease in impact over time as the technology evolves.

Some of the info I found just search the net for http FAQ.
