I’ve been having this issue very sporadically (sometimes a couple times a week, sometimes once a month). I’m curious as to how the more veteran folk here would try and narrow down the cause of this issue.

I can provide more info if needed!

    I am able to access the Linux shell locally or on the local area network. From within I can ping the gateway, but nothing beyond that.

    Is there a tracert equivalent for Ubuntu?

    I will say I get this error when trying to ping www.google.com:

    ping: unknown host

      The tracert equivalent that I use would be traceroute or mtr. If you can get a response from the gateway and access the server locally, it would indicate an IP routing issue as local subnet traffic is working.

      Instead of pinging a domain name, what happens if you ping a public IP like Google DNS (8.8.8.8)? The error you’re seeing could be related to a DNS resolution issue although that should not affect access to your server.

        Ill try that next time it hiccups. I was thinking I should have pinged an IP address after I was pasting the unknown host error 🙃.

        In further hindsight I shouldn’t have restarted the server so I could try the things during our conversation. 🙁
