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?

I am a DNS administator at my employers and notice that on my employers network that aus3.mozilla.org and aus4.mozilla.org seem to be returning NXDOMAIN both with our on prem DNS and via the public dns providers when a browser attempts update it can fail.

Have other Australian users reported such behavior and are these hosts still valid
