I set up Invoice Ninja for my business invoicing needs. After logging in, refreshing the page would immediately kick me back to the login screen. After a deep troubleshooting session, the culprit turned out to be a CrowdSec AppSec rule designed for Langflow AI — misfiring on Invoice Ninja’s /api/v1/refresh endpoint.

I replaced my standard Nginx Proxy Manager instance with NPMPlus (an enhanced fork) and integrated CrowdSec for automated threat detection and blocking — including Cloudflare Turnstile captcha challenges. The whole stack runs in Docker, managed via Dockge, and sits behind itself as a reverse proxy. Here’s exactly how I did it, including the gotchas I hit along the way
A technical walkthrough on self-hosting the Immich photo library inside a lightweight, unprivileged Proxmox LXC container. It covers securely mapping a TrueNAS NFS share to bypass unprivileged LXC permission errors, passing through an NVIDIA GPU (GTX 1080ti) to the container, and using Dockge for deployment. The result is a highly secure, hardware-accelerated photo backup system with blazing-fast video transcoding and AI facial recognition.
