after configuring wireguard settings from my VPN provider’s configuration files, I then get this message

only data accessing subnet 0.0.0.0/0 will pass through the VPN. data leaks may be possible

Have searched through posts, one previous post resolution was to not care as only using vpn to access home network. I want to use VPN for travel and privacy at public WIFI, what is needed to properly mask my IP address?

Which vpn provider?
Please change the conf file AllowedIPs line:

For instance:
change

AllowedIPs = 192.168.110.2/32

to

AllowedIPs = 0.0.0.0/0, ::/0
