Firefox Community Forum

Hi, all experienced peoples are here I got strange issue with firefox lately. my site sometimes https://avsogirl.net/ not loads at all, just shows “server not found” look at the image.

i first thought maybe server down, but i checked with curl and ping, server responds fine. also tested same site in chrome and edge, loads normal there, no error. i tried clearing cache, disabling addons, even fresh profile. still same. only firefox gives this dns error.

i use dns-over-https in firefox, and i also have proxy config for work. maybe firefox handling dns/proxy different? when i switch off doh, sometimes page loads, sometimes not. so looks like firefox network stack problem, not site issue. anyone else facing same error?
