pfBlocker Errors - Requesting Clarifications

[pslinn]

In reviewing the error.log for pfBlocker, I have noticed a large number of error messages like the following:
PFB_FILTER - 2 | php [ 05/10/24 04:15:00 ] Invalid URL (not allowed) [ https://feodotracker.abuse.ch/downloads/ipblocklist_recommended.txt ]
PFB_FILTER - 2 | php [ 05/10/24 04:15:00 ] Invalid URL (not allowed) [ https://sslbl.abuse.ch/blacklist/sslipblacklist.txt ]
PFB_FILTER - 2 | php [ 05/10/24 04:15:53 ] Invalid URL (not allowed) [ https://cdn.jsdelivr.net/gh/neoFelhz/neohosts@gh-pages/basic/hosts ]

When I copy and paste the URLs in a browser address bar I can immediately access the file at the link.

As such I am confused why these error messages are showing up.

Any ideas?

Peter.
