Describe your problem

I always encounter an error in step 7 when executing the build image command. The error message seems to indicate a network issue, but when I click on the error link, it redirects to the browser where I can download the corresponding resources. Please help me solve this problem. Thank you very much

Complete Command：docker build --platform linux/amd64 --build-arg LIGHTEN=1 -f Dockerfile -t infiniflow/ragflow:nightly-slim .
Code version：0.19.0

Start with the repository's Dockerfile and reproduce the reported command, focusing on step 7. Capture the complete error output instead of relying on the screenshots, then check whether the failing dependency download or Docker networking is responsible. Done means a reproducible diagnosis and a documented fix or required build change.
