How to Stop the Repeating UDP Message Spamming Logs

An option in UDP Messaging has to be disabled to stop the error message from constantly logging

Unreal Engine 5 repeating UDP messaging warning — Warning: UDP messaging encountered an error. Auto repair routine started for reinitialization

Software Versions: Unreal Engine 5.4.4

New projects in Unreal Engine 5 have the following warning that spams the logs every second, Warning: UDP messaging encountered an error. Auto repair routine started for reinitialization.

Remove the warning by going into Project Settings (Edit -> Project Settings) and disabling Enable Transport under the UDP Messaging section. By default the value is true.

Unreal Engine 5 UDP Messaging Enable Transport enabled — Unreal Engine 5 UDP Messaging Enable Transport set to true

Unreal Engine 5 UDP Messaging Enable Transport disabled — Unreal Engine 5 UDP Messaging Enable Transport set to false

After setting Enable Transport to false I click Set as Default to further save the option and keep the option disabled.

Going back into your project the warning Warning: UDP messaging encountered an error. Auto repair routine started for reinitialization should no longer be spamming your logs.
