Containers can't connect to internet after setting up PiHole

[MrDingleberryHandpump]

I am new to TrueNAS Scale and Kubernetes, so please forgive me if this is a stupid question.

I added TrueCharts to TrueNAS, and installed Pi-Hole, Filezilla and several other containers. Everything seemed to work great.
Then I changed the default DNS in my router from Googles DNS to Pi-Hole. All my devices (laptops, phones, etc) now uses Pi-Hole, and ads are removed - great!

However, then I discovered my other containers no longer can resolve DNS requests. I am guessing this has something to do with inter-container communication, and that they cannot connect to Pi-Hole.

So now the question is, how do I fix it?

I'm going to suggest you hit up the truecharts discord for any assistance regarding pihole, but you should also make sure your Server is not pointing to it's self for DNS, it should continue to point at an upstream/standalone DNS server
