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.
