Adguard home and local hostnames


New Member
Hi all
I wanted to replace pi hole with adguard home, and I set up everything successfully but one thing:
I cannot access anymore to my local servers anymore through their hostnames, only via the IP
My router's IP ( is set up in the private DNS server and the clients appear with their hostnames in the adguard dashboard
However I cannot access for example to ds214.casita, "casita" being my local domain

I tried to put [/casita/] in the upstream DNS but when I hit the test button I have an error message saying that this upstream us not answering requests...

Any help on this?
Adguard version is 0.107.38
