Research direction
Start with the reported concurrent-download scenario and the FileDownloader 1.7.7 log, especially the request and response headers around the 503. Reproduce the failure with one download followed by a second and compare it with a single download. Done means identifying whether the library or the file server causes the 503 and documenting or fixing the confirmed cause.
