Start with script/environment_check.sh and the Kestrel proxy startup shown in the logs, then reproduce both host acceleration and system acceleration on Ubuntu 24.04. Trace the bindporterror and the failed GitHub connection; done means host mode starts without a port-binding error and system mode successfully loads GitHub.
