Permission problems on the box, do you have root access? If so, try do some chmods to your file structure before attempting another start of kong(don’t do this in prod as I am giving the allow all chmod).

chmod -R 777 /usr/local/kong
chmod -R 777 /usr/local/share/lua/5.1

This may work, may not. worth a shot I suppose. Enterprise questions can be directed directly with your Kong rep during your enterprise trial too with Kong support team.

Anytime! Take care :slight_smile:
