Any debug log?

bcookatpcsd commented 1 month ago

Did not have enabled.. will enable and share

fwiw: the two controld domains is the same host.. just the https was using all the bandwidth

smartdns.log smartdns-audit.log

I had recreated the container not realizing there was a '/var/log/smartdns/' in the container..

Please let me know if there is nothing of value in there..

From the log, it appears that only three upstream servers were added, which is different from the configuration. No other issues were observed.

recv query packet from 127.0.0.1

There is a prefix dns server on the same device as smartdns , which only forwards part of the query to smartdns. You should investigate issues with that prefix dns server.
