When I run the following command: `nc -luvp 9090`, I get the error: `getnameinfo: Temporary failure in name resolution`

I've scanned the internet in search of an answer, but none of them were valid:

* <https://github.com/bonzini/netcat/issues/2>: not answered
* <https://www.reddit.com/r/linuxquestions/comments/fa8l7s/issue_running_netcat_lvp/>: not answered

I found this link: <https://unix.stackexchange.com/questions/504963/how-to-solve-a-temporary-failure-in-name-resolution-error>
And tried the most upvoted answer. My results:

**I'm using NordVPN, which uses its own DNS servers. But I tried disabling it completely, and I get the same exact result. I'm afraid it messed up with my DNS config file and/or firewall rules.**

I'm kinda new to Linux and feel a bit lost.
