I’ve been using Adguard Home for a few months and everything is working well.
Last night I logged into my router and noticed the /tmp folder was full. I cleared the logs and changed the retention period to prevent it happening again. I noticed that I still had enable plain DNS enabled.
Encrypted DNS is up and running with a self-signed cert.
I tried disabling plain dns and it broke DNS for my network. My Wi-Fi clients all showed connected no internet.
Is this normal behaviour? Do I need to configure something else before I can force encrypted DNS?
Thanks.
