Hi,

I have 2 machines (Win10 and Win11) with FF 140.3.1esr (32-bit) installed which demonstrates the same failure when I enter one site's url:

PR_CONNECT_RESET_ERROR

Chrome at the same machines goes at this url w/o any failures. Any ideas what to change on "about:config" in FF to allow it opening this url w/o such error?

Can you try flipping network.http.http3.enable in about:config and seeing if that fixes it?

I'm wondering if this has to do with something intercepting this request.

When I connect to that site, sometimes it redirects to lawfilter.ertelecom.ru (particularly if I use http)

If you look at the URL in your screenshot, it's http not https which means that somehow the redirect to https didn't happen properly.
