Where to find black hole datasets

TL;DR Summary
Downloading large XMM-Newton catalog (4XMM-DR9 EPIC) - keeps failing
Hi everyone,
I'm trying to download the 4XMM-DR9 EPIC Source Catalogue for some X-ray spectral analysis near black holes. The download links on the XMM-Newton site are broken, and the archive ones are working but the actual download keeps failing before reaching 10% completion (it's a large file).

Additionally, I'm open to suggestions for similar datasets. I'm specifically looking for X-ray spectral data of sources at different distances from strong gravitational fields (particularly near black holes). The key is having good spectral resolution and reliable flux measurements across different energy bands.
