Changing line 86 of the source code file cocopp/archiving.py in the Python local site packages folder of the system to

coco_url = "https://numbbo.github.io/data-archive"  # new data location

should be a quick fix.

[nikohansen]

pip install --upgrade cocopp

should now fix this issue. If this does not install a newer version, use

pip uninstall cocopp --yes

first (possibly several times).
