URL Blacklist update from Univ. Toulouse doesn't work

This will be great, because I can set the firewall setting “outgoing” to “blocked” again.

Yes, great news!

The U. Toulouse list is unreachable for long time.

Automatic blacklist update [ Last successful blacklist update was 32 days ago ]

I am trying to use a list with a good availability e.g.
https://urlhaus.abuse.ch/downloads/csv_online/

They allow update interval of 5 minutes or more. So once a day shouldn’t be an issue
But I am still getting the same error:

installpackage[urlfilter]: 	URL filter blacklist - ERROR: Not a valid URL filter blacklist

Or even a mirror of the University of Toulouse Blacklist:

installpackage[urlfilter]: 	URL filter blacklist - ERROR: Not a valid URL filter blacklist
