Не могу получить доступ к нескольким конечным точкам с помощью apt update или wireguard, но может использовать netcat для связи с ними.

У меня возникла проблема, когда мое устройство Ubuntu не может подключиться к нескольким конечным точкам, когда я пытаюсь это сделать.

Устройство Jetson Nano

Вот мой вывод при запуске sudo apt update:

Но когда я запускаю netcat на одних и тех же адресах:

      jetson@jetson:~$ nc -z -v 91.189.88.152 80
Connection to 91.189.88.152 80 port [tcp/http] succeeded!

То же самое относится и к моему проводному соединению. Я не могу подключиться к своей конечной точке с помощью wireguardm, но я могу с помощью netcat, например:

      jetson@jetson:~$ nc -z -v -u my.wireguard.endpoint 5555
Connection to my.wireguard.endpoint 5555 port [udp/rplay] succeeded!

В журналах wireguard ему никогда не удается достичь конечной точки:

      [Fri Nov 26 11:46:09 2021] wireguard: my_vpn: Sending handshake initiation to peer 3 (my.wireguard.endpoint:5555)

В целом на устройстве я могу правильно получить доступ к Интернету:

      jetman@camera:~$ ping google.com
PING google.com (142.250.70.206) 56(84) bytes of data.
64 bytes from google.com (142.250.70.206): icmp_seq=1 ttl=58 time=36.9 ms
64 bytes from google.com (142.250.70.206): icmp_seq=2 ttl=58 time=17.9 ms

Как это может произойти? Ведет ли себя netcat иначе, чем обычное интернет-соединение, которое он может пройти, но никакое другое?
