Linux cook failure: Error: Failed to initialize libwebsockets

Development Platform & Builds

Hi. I’ve been getting a failure during builds for Linux (Shipping) on an Editor (5.5.1) running on Linux (Kubuntu 24.10, libwebsockets-dev 4.3.3):

AutomationTool exiting with ExitCode=25 (Error_UnknownCookFailure)

with the following in the cook log

LogWebSockets: Warning: Lws(Error): OOM allocating 1073741816 fds 
LogWebSockets: Warning: Lws(Error): ZERO RANDOM FD 
LogWebSockets: Error: Failed to initialize libwebsockets

This is the only error I could find in the cook log. Any idea what this would be caused by, considering that I have libwebsockets-dev installed?

Hi there @meoblast001

Welcome to the Unreal Engine Community Forum! I pulled a thread from another developer having a similar error. See if this helps! AutomationTool exiting with ExitCode=25 (Error_UnknownCookFailure)
