Feb 02, 2026This error usually means the NGINX App Protect compiler service is either not running or lacks the permissions to write its configuration files.
Quick Fix Steps
- Restart the Services: Ensure the background agents are active. Run:
- sudo systemctl restart nginx-appprotect enforcerd
- Fix Permissions: The error compile_error_msg.json failed suggests a lock on the directory. Run:
- sudo chown -R nginx:nginx /opt/app_protect/
- Check Memory: App Protect needs at least 4GB of RAM to compile. If your VPS is low on memory, it will timeout at the 45-second mark.
- SELinux: If using RHEL/CentOS, temporarily run setenforce 0 to see if a security policy is blocking the fstat() call.
i hope this will help you to fix this issue!
