Behavior
I use a dockerized nebula-sync to keep both my piholes in sync. However the 2nd pihole (the one receiving the replication) however often goes down and it seems like it takes 5 minutes to reboot the FTL which doesn't seem normal to me...
I also found this issue on nebula-sync's github but doesn't provide any solution: lovelaze/nebula-sync#69
