Hi, Destiny's error codes are set up with names to help players quickly find the help articles about them, to help understand what's causing the issue. The Marionberry error code article mentions multiple times that Parental Controls in the routing device of a network can cause this error to show up. Parental Controls on most consumer routers are simple DNS blockers or redirectors, which ends up correlating with the issue you're experiencing. I believe there's probably some misconfiguration on your router causing the DNS to not properly redirected for the game. Unfortunately there's nothing that Bungie can do, as this is a very specific situation, so i recommend you look up documentation for the packages you're using on OpenWRT and maybe help from their community.
