Hi all, does anyone know what this could be about?
Absolutely all sites open except instagram.
Proxies were raised on linux, it can't be that 3 mobile proxies/ports banned instagram at once?

HTTP/1.0 502 Bad Gateway
Connection: close
Content-type: text/html; charset=utf-8

curl: (56) Received HTTP code 502 from proxy after CONNECT
ping gives this error
