    Unplugging my WAN cable has resulted in my wifi clients not being able to connect my router (Asus RT-N16), and my LAN clients not being able to see my DLNA server (DLNA server is on another LAN client machine, not on the router itself).

    I plugged the cable back in, and looked at my logs. The same message was shown over and over:

    Jun 10 21:27:24 snowman daemon.debug dnscrypt-proxy[6005]: resolver timeout (UDP)
    Jun 10 21:27:24 snowman daemon.debug dnscrypt-proxy[6005]: resolver timeout (UDP)
    Jun 10 21:27:24 snowman daemon.debug dnscrypt-proxy[6005]: resolver timeout (UDP)
    Jun 10 21:27:25 snowman daemon.debug dnscrypt-proxy[6005]: resolver timeout (UDP)
    Jun 10 21:27:25 snowman daemon.debug dnscrypt-proxy[6005]: resolver timeout (UDP)
    Jun 10 21:27:28 snowman daemon.debug dnscrypt-proxy[6005]: resolver timeout (UDP)

    At first, I thought my router cpu usage shot up to 100% because of the repeated requests, though I tested this a second time and it was only at 10%. I am not sure if this is actually the issue, because I don't see why dnscrypt would be needed for my LAN DNS requests. My router is the DHCP and DNS server on my LAN, and all of my LAN clients have statically assigned dhcp ip addresses. I think dnscrypt was caught in a loop of some sort, which might have affected dnsmasq from handling any DNS and DHCP requests.

    I am interested in finding a solution, because this behavior might also suggest that my wifi and other services on my LAN would stop working if my internet connection was to go down.

    Is there a way to limit the number of dnscrypt-proxy retries per minute?
