I use droplet with ubuntu 18.04, openlitespeed and wordpress. Suddenly, my website is down. SSH cannot be accessed from external, but it can be accessed from the internal/web console.
For a temporary solution, I followed this instruction https://www.digitalocean.com/community/questions/no-internet-connection-after-droplet-reboot?answer=54647
But, as I said, it just temporary, when I reboot my droplet, it happens again.
Adding some nameserver into /etc/resolv.conf just temporary solution.
Problem is What should I do to make permanent solution? and I cannot use apt-get update command, got some errors “Failed to fetc” although I changed /var/lib/lists.
