@Ghislaine @anemone @mischievoustomato Lets start with the fact that systemd has an integrated networking module that may re-route all your internet requests through the google DNS service behind your back, no log file will ever show that the DNS lookup of your requested webpage through your prefered DNS failed and instead systemd decided to send that request to the google DNS server, only way to know is to check from your browser or ping what DNS server is being used to resolve your look ups.
