Ubuntu server 20.04 will not automatically reconnect to internet after an internet outage or by unplugging the ethernet cable

Using Ubuntu 20.04 LTS server connected to the internet via Ethernet cable.

When my internet service provider has an outage I have to restart my server to regain internet access.

All my other devices seem to reconnect just fine via WiFi.

What could be the problem?

I also just tried unplugging the Ethernet cable manually and plugging it back in and the same behavior happens.

I don’t have internet and need to restart the server. Thanks.

Edit: I have found out that the use of my VPN is causing DNS issues. I am using Mullvad VPN via its CLI and have internet connection on bootup up until any internet disconnection be it physcially by unpluging the internet or ISP outage. I can ping 8.8.8.8 after the fact but not google.com. I think the VPN has issues with the systemd-resolved service. Again, I have no issues when I deactivate the VPN.

Скорее всего, вам нужна новая аренда DHCP.

Вы можете обновить это несколькими способами, вот два простых:

• из командной строки выполните: sudo service network-manager перезапустить
• с рабочего стола, перейдите в Network Manager, отключите, а затем снова включите сеть.
