        When unbound restarts current user (from LAN etc) are not disconnected.
        If unbound starts to restart several times a minute (you showed just one !) then you should start to look why unbound is doing so. In your case, incoming DHCP requests from LAN is not restarting your unbound.

        The girst two lines of your log shows that unbound itself can't connect to the net (the 8.8.8.8).

        Do you really need to forward DNS requests ? Do you need to have handled all your DNS requests to Google ?
        What happens if you make unbound work as a resolver ?

        If your upstream WAN connections goes down, and unbound depends on remote DNS resolvers (the 8.8.8.8 etc) then I can imagine unbound restarts. This would also explain why users get disconnected.

        No "help me" PM's please. Use the forum, the community will thank you.
        Edit : and where are the logs ??

          Thanks for the reply, i had to cut the log because it was not letting me post that log as it was marking me as spam to post.
          This is the current log

          Do you really need to forward DNS requests ?

          well im using DNS Resolver but should i disable DNS query Forwarding?

          Do you need to have handled all your DNS requests to Google ?

          Well funny thing on the general setup im using 1.1.1.1 and 1.0.0.1 as primary and secondary so not sure where the 8.8.8.8 is coming from.

          What happens if you make unbound work as a resolver

          Well isn't it currently as working as a resolver? or do i have to uncheck DNS query forwarding?

          Thank you again
