Error "Upload failed" after uploading text file to new knowledge base

Discussion

No matter what format of text file is uploaded, it always shows an error “Upload failed”, and the next step becomes grayed out. What could be the issue?

Please provide the container logs instead.

Check F12 to see if it’s a 500 error. If so, it might be due to a mismatch between the Nginx port configuration and the actual access port, causing static resources on the page to load normally, but all API requests requiring reverse proxy to fail in forwarding.
