I don't know if this is related but now it simply could not resolve https://www.aviationweather.gov and www.noaa.gov. The result is the same through ping and wget.
However when I try ip address of www.aviationweather.gov in browser it works. ------------------------------------------------------------------------------- $ systemd-resolve 140.90.101.207 140.90.101.207: resolve call failed: Address '140.90.101.207' does not have any RR of requested type $ wget "https://140.90.101.207/adds/dataserver_current/httpparam" Connecting to 140.90.101.207:443... connected.
