Check the /etc/resolv.conf file, it should look like this
# This file was automatically generated by WSL. To stop automatic generation of this file, add the following entry to /etc/wsl.conf: # [network] generateResolvConf = false nameserver 172.17.48.1
The nameserver IP address can be obtained by typing in
ip r l default
Be sure to restart the wsl in powershell using
wsl --shutdown, and starting up the WSL again.
Also, be sure that you've added your sites to
/etc/hosts and the Windows hosts file
Lastly, sometimes services are acting out on WSL2, so you can just restart them like
sudo service mysql --full-restart
dnsmasq whichever is causing issues.
Last but not the least you can try to restart the valet using
This should kickstart the local sites.
