Can't connect through Wireguard on Ubuntu

[zendata 0]

I have been attempting to connect to AirVPN servers through Wireguard on Ubuntu 24.04.1 LTS, but after I connect I cannot access the Internet. I followed the directions here: https://airvpn.org/linux/wireguard/terminal/ On the Config Generator, I selected Linux, then the Wireguard UDP protocol, then downloaded the Europe config. I renamed it to wg_europe.conf and placed it in a folder named airvpn. Then I ran:

sudo wg-quick up /home/myuser/airvpn/wg_europe.conf

which worked successfully. From here on out, I cannot access the Internet. Going to google.com or anything else in Firefox results in a Server Not Found. ping 1.1.1.1 and ping 8.8.8.8 both fail, but I CAN ping the IP address under [Interface] in the wg_europe.conf file. When I run `sudo wg` in a terminal, I get this output:

interface: wg_europe
  public key: <redacted>
  private key: (hidden)
  listening port: 46776
  fwmark: 0xca6c
    
peer: <redacted>
  preshared key: (hidden)
  endpoint: 213.152.162.76:1637
  allowed ips: 0.0.0.0/0, ::/0
  latest handshake: 3 minutes, 49 seconds ago
  transfer: 23.30 KiB received, 88.00 KiB sent
  persistent keepalive: every 15 seconds

When I run `wg-quick down /home/myuser/airvpn/wg_europe.conf`, I still cannot connect to the Internet and I have to restart my computer every time to start over. Some help would be greatly appreciated!

Can you enable logging/save log to a file and post it?

Hello!

Please test again with ufw disabled to quickly discern whether an ufw custom rule is the "culprit". From a terminal enter the following command:

sudo ufw disable

You can later re-enable ufw if needed with

 sudo ufw enable

Kind regards
