ERR_CONNECTION_RESET with facebook cdn

My LAN with clients works fine a few days ago, but suddenly one issue occurred with the facebook cdn with this wildcard url https://.fbcdn.net/

This happened only when I’m using public IPs issued by LACNIC

The error received with Facebook, Instagram, AirTM and some others is net::ERR_CONNECTION_RESET or net::ERR_TIMED_OUT on the browser.

Any idea on this ?

I’m using RB3011

When things misbehave, what does /tool traceroute show? Sometimes also ISPs have their share of problems …

Can you try this?
