How to fix the lack of Internet (LAN is present)?

Question

linux

Installed Debian - everything is fine (there was Internet), set up packages for little things (ssh, samba), transferred the system unit to the server room, plugged it into another port - the Internet was gone. Lokalka responds and is seen well.
The port is working - I tried to connect a laptop - the Internet is excellent.

In administration, he is not very strong, please tell me what to do?

Answer 1

Judging by ip r there is no gateway for the Internet. Probably because the word gateway is incorrectly specified in /etc/network/interfaces.d/enp2s0.
But it is not clear why it worked ... Maybe the gateway was manually registered and it worked until the first reboot?

Answer 2

Perhaps the port is in a different VLAN.
