Dns issues

[lixo12nitb]

Hello all!

I’m having an issue with name resolution on my environment on my Android phone. I'm using private resources, and the newt VPN is working, and I can access all resources by IP, but when I use the local dns, it fails to resolve.

In the Pangolin app on Android, I have my two internal DNS servers configured as the primary and secondary upstream DNS. I’ve tried enabling/disabling DNS override and DNS tunnel, as well as enabling both at the same time, but I still can’t resolve names.

Something I find strange, though I’m not sure if it’s expected, is that in the JSON file inside the app’s status, the dns_servers field always shows 100.96.128.1. I don’t know if this is something I misconfigured or a bug in the app.

I’m using the latest versions available as of today.

Any help would be appreciated!
Regards

Your two internal DNS servers are behind the VPN, but Tailscale (Pangolin) forwards DNS requests through its own resolver by default.

If the Tailscale resolver doesn’t know about your private domain, queries will fail.

Android may also ignore custom DNS in VPN apps if “DNS override” isn’t working correctly.
