HTTP1 should be fine on most webservers or?

or is it already so that some servers dont support that anymore?

I have encountered some that reject HTTP1 requests

Possibly CloudFlare, or that was coincidental

you mean 1.0? Or 1.1?

0.9, 1.0, 1.1

HTTP 0.9 has no headers

i mean whatever people mean if they say the server does not support HTTP2

If 1.0 didn't work that's a bit odd but not a huge shock. If 1.1 doesn't work one may well ask if it counts as a webserver at all

HTTP2 is barely HTTP really. It's just some other thing

i enabled http2 support in Gajim a few releases back, since then many users complain that its worse in some way or does not work at all

Could be websites rejecting anything that doesn't look like a standard (popular) browser request in an attempt to fight LLM crawlers?

no, we are talking about xmpp http upload servers

Having links to investigate would really help

I'd expect most such to not support http2 but I assume you have fallback

the problem is with the servers that support http2

there problems are reported

im not interested to debug http servers and libraries, i just plan to disable it and go back to http1 only

the problems are not of the nature "does not work at all" which is probably easy to debug

the problems are stuff like, "takes 20 seconds longer than usual", "stuck at 100%", or very technical errors from the lib, like some frame windows are not big enough

Oh, I’ve experienced the "stuck at 100%" bug against JabberFR, which uses a very standard nginx with h2 enabled.

So it is an issue of your HTTP library?

as said, i dont debug http libraries, nor servers
