Repeated errors in logs #944

Closed drbobnz closed 3 months ago

drbobnz commented 3 months ago

Hi - I repeatedly get these error messages in my logs, am not sure if they are issues with Technitium DNS or not (or if this is normal or not) - any help appreciated!

  1. System.ArgumentException error - there's a lot of them
  2. DHCP address offers, a few seconds apart - note the weird character in the device name - but the device doesn't seem to accept the offer as far as I can tell
  3. DnsServerCore.Dns.DnsServerException: Failed to set records error (seems to relate to 4 below)
  4. Repeated DHCP Server updated DNS A record / DNS PTR record from one of our Apple TVs.

Log extracts below:

Thanks for reporting these issues. Will get them fixed in the upcoming update.

ShreyasZare commented 3 months ago

Technitium DNS Server v12.2.1 is now available that fixes this issue. Do update and let me know your feedback.

drbobnz commented 3 months ago

Thanks so much! I've updated today, will review the logs over the next day or so.

I also have another bug that I will probably log. Isn't related to this issue and this update didn't fix it (in short, if I reboot the server, DNS requests for devices for one network range fails until I untick 'Enable DNS-over-HTTPS', save settings, and then retick and save settings).

Do check the DNS logs to see if there are any errors logged for this. Share any error log you find.
