When I unblock the Facebook address, the app opens as expected.
I'm not blocking any NTP. My home servers rely on it (just TrueNAS checks time every 3 minutes...), but I do block DNS outbound to force using my own DNS.
You are blocking NTP though. Look at your image, all the way at the bottom.
I'm going to assume that hopefully OP knows how DNS works and meant he blocks all outbound DNS requests from his devices and sets a specific DNS for his external queries from his FW/Router. I do the same thing.
However, he is blocking NTP right there so who knows.
PCap is just a packet capture. "Closed" in this context just means the connection is no longer currently active.
