Description

Hi, I have a domain with Cloudflare proxy... a Proxmox with LXC where NPM is... and another LXC with another Docker with a website in Nextjs...
My website works correctly, but randomly gives a 502 error. I have to wait a few seconds and try again and it happens... again... I already enabled the asset cache and disabled it... I also deleted other domains... but it keeps doing the same thing...

Research direction

No files, tests, or entry points are identified. Start by reproducing the intermittent 502 across the Cloudflare proxy, Proxmox LXC, Nginx Proxy Manager, and Docker/Next.js layers, then use the relevant logs to isolate the failing layer; done requires a reproducible cause and a confirmed fix.
