Version 10.0.18 Cannot resolve domain name over VPN

I am on Mint Linux 19.1 and trying to access our database via a VPN connection (no ssh tunnel). I can connect fine if I enter the database IP address, but if I put in the internal database domain name (we are on AWS), it fails to resolve the name. I can resolve the name fine on the command line using nslookup or dig.

I have resolved the issue. It was not a problem with DBVisualizer, but was related to systemd-resolved and how it handles VPN DNS.

For those in the same situation, here is how I resolved it.

1. Modify the conf file link for systemd-resolved

sudo rm /etc/resolv.conf

sudo ln -sf /run/systemd/resolve/resolv.conf /etc/resolv.conf

2. Update the order of resolution in /etc/nsswitch.conf, by placing the dns before the mdns4_minimal

sudo vi /etc/nsswitch.conf

move dns from the end of the line before mdns4_minimal

3. Reboot
