Edit: switching to https://sky.rethinkdns.com worked, thanks for all the suggestions!

Hope this is the correct forum to ask this question.

I’ve recently switched to RethinkDNS and quite like it. I’ve run a PiHole on my home network for a while, and Rethink finally gives me the same functionality and customizability while away from my house.

When I’m at work at [REDACTED BIG CORPORATION] my Internet won’t connect at all while on company wifi with Rethink active (“No Answer” response to all queries). I just turn DuckDuckGo app tracking protection on instead (also technically a VPN according to my phone), and the Internet works. CyberGhost VPN behaves the same as Rethink, so I’m unsure why DDG doesn’t run into issues.

Does anyone know of a way to automatically swap between VPNs while on certain networks? I’m sure it is possible to do so with a GPS fence and SmartThings, but I don’t want to give that app (or any for that matter) location permissions.

If anyone has any suggestions on how to do this (I’m fine using apps outside of Google Play, as you can infer from my use of RethinkDNS and DDG in the first place), I’d love to hear them!

Cheers, Hank
