NordVPN 3.18.4 fails to resolve google.com or any domain really

these are my settings above for nordvpn. the next section is for showing connection to nord, curling google, disconnecting from nord and attempting to curl again.

pi@rp1:~ $ nordvpn connect mexico
Connecting to Mexico #106 (mx106.nordvpn.com)
You are connected to Mexico #106 (mx106.nordvpn.com)!
pi@rp1:~ $ curl google.com
curl: (6) Could not resolve host: google.com
pi@rp1:~ $ nordvpn d
You are disconnected from NordVPN.
How would you rate your connection quality on a scale from 1 (poor) to 5 (excellent)? Type 'nordvpn rate [1-5]'.
-pi@rp1:~ $ curl google.com
success (was html and cant figure out how to properly use code blocks in github )

Reference, i was recently using NordVPN 3.17.0 and did not have these issues. might have to go back to that version to be able to use nordvpn fully. Currently using 3.18.4 which is the latest version for linux.

even with disabling DNS to use nordvpn dns i cant get to google or any website via domains.

Hi, thank you for a patience, could you give us latest logs from the app? At the time when you see the problem is taking place. We tried to reproduce the issue on Raspberry Pi 4 which we have - but unfortunately not able to reproduce the situation when VPN connected and DNS not working (i.e. can not resolve domain name). Logs would give us more information what is happening.

[mrpainte]

can you give me direction on how to obtain the logs? checking /var/log/nordvpn/daemon.log does not seem to be the true log file

[mrpainte]

I found a command that might work and have sanitized the result from the last yearish of data.

journalctl -u nordvpnd > nordvpn.logs

however i am unsure if this is the proper logs you are looking for. Nor if i should drop the file here on github due to possible keys?

i do see this log however (last line).. with nordvpn enabled, it seems DNS is trying to access my routers DNS instead of nordvpn's DNS? i find that odd

[keliramu]

Ok, I got it, problem is that app is trying to use your router as a DNS server.

[mrpainte]

yeah. which i know works since when im off the VPN it works but when on the VPN it fails. i did install 3.18.2 and it is working but 3.18.4 is not

@keliramu I'm seeing this issue in 3.19.1 as well. Times are in EDT. 192.168.1.57 is my local adguard box, IPv4 of the device using nordvpn is 192.168.1.49. Running Ubuntu 22.04.
