In case you are experiencing issues with your NordLayer connection, resetting your network settings is a viable option to resolve them. A full re-boot of your Linux device should always work, but there also are more granular ways.
Reset network
In most cases, Internet connection is made via Network Manager:
sudo systemctl restart NetworkManager
Temporarily deactivate Firewall
For debugging issues, it can be helpful to deactivate the Firewall temporarily to see if that changes anything. To list Firewall rules:
sudo nft -s list ruleset # list rules
sudo ufw status # Ubuntu
The Firewall can be cleared until the next reboot:
sudo nft flush ruleset # clear all rules
Please note that these changes will be temporary and reverted after device reboot.
