Has anyone else seen issues with DNS lookups against a local DNS server recently?
The last email (sent to a local mail servrr) was October 7, so I know it worked then. Since then, I know I applied a homeassistant update. Due to the fallback DNS setting to cloudflare, I had no idea local DNS broke.
I'm relatively new to homeassistant and was busy with other tasks last night, so troubleshooting w as limited once the email server setting was flipped to an IP and certificate verification disabled.
I did figure out that "dig @dns-ip hostnamr +cd" does work, and that without, the dns server is returning an error. Didn't write that down because i was in a rush.
I'll be digging a lot deeper today, but if anyone has ideas of what happened, I'd love to hear it.
