+#### OVH/SoYouStart Game Firewall Incompatibility Issue
+The OVH GAME filter type `minecraftPocketEdition` currently does not work and you must use the `Other` type.

+If you would like to continue using the filter type `minecraftPocketEdition`, you may disable the incompatible security feature by adding `-DGeyser.RakSendCookie=false` to your Java server's (or Geyser Standalone proxy's) startup flags.
