Docker Pulls Fail with EOF on Large Downloads
Asked by

I'm trying to build an automated job-extraction project using Docker, n8n, Ollama, Firecrawl, and SQLite. I'm new to development and still learning how all the pieces fit together. Docker and WSL are working, and small downloads complete normally, but larger downloads—such as an Nginx image—fail partway through with an EOF error. The failure happens over both my home Wi‑Fi and a mobile hotspot, and I'm not using a VPN. Could my network, router, or connection settings be interrupting large Docker downloads?

An EOF during a large image download usually means the connection was interrupted before Docker received the complete response. Try pulling the same image from a different network first. If it succeeds there, Docker is probably fine and the problem is somewhere in the original Wi‑Fi path, such as the router, ISP, unstable signal, or MTU settings. Checking router firmware and testing with a wired connection would be useful next steps.

Since the download works over a different hotspot, I’d focus on the home network rather than n8n, Ollama, or the rest of the planned stack. First confirm that ordinary large files download reliably on that Wi‑Fi. If they also fail, the issue is broader than Docker. If only the container registry fails, check whether the router has security, proxy, DNS, or traffic-inspection features enabled and temporarily disable them for testing.

It would help to capture the exact image and complete error output, but the fact that small downloads work does not rule out a network problem. Large transfers are more likely to expose brief disconnects or packet-size issues. Try a wired connection if possible, reboot and update the router, and compare results with another device on the same network. If every device has the same problem, contact the ISP or investigate the router’s MTU and filtering settings.

MapleRook47: I tried another mobile hotspot and the image downloaded immediately. That points pretty strongly to my home network, although replacing the entire Wi‑Fi setup isn’t really practical for me.
