Try the 'Talos' URL yourself in a web browser.
You should obtain some big list with IP's etc.
Or, the server that hosts the file is in a bad shape. It throws a "404" (the file was not found) in your face if it can't give you what you're asking for.
This happens. Servers go wako ones in a while. All depends on the admin of that site.
Maybe the file changed it's name ?

These lists, used by "pfBlockerNG", have to be maintained, also by you. Nothing is static, they can change.

I wonder if its the redirect it's not liking, I just noticed this.

One point for @NogBadTheBad : you just discovered that a browser is probably somewhat smarter as the 'wget' or 'curl' used by 'pfBlockerNG'.

linuxmanr4

It's exactly the same for me.

I provisionally changed the url to Amazon hosted and it seems to work.

I took note of the previous url in case it works again.

Greetings.

@linuxmanr4 Your link doesn't seem to work anymore. I believe the extended information has caused it to expire. Same with me. Things are munged server-side.

linuxmanr4

That's right @provels , it worked for a while and then it did the same thing again.

I am going to report this problem to pfBlockerNG.

RonpfS

@linuxmanr4
There is an "Expires=3600" in the redirect URL

The user agent curlopt was resulting in a 403 from Cloudflare, seems they didn't like Google Chrome 43 circa 2015.

I changed my user agent to plain old 'curl' and everything is working again.

edit /usr/local/pkg/pfblockerng/pfblockerng.inc line 118:
from:

$pfb['curl_defaults'] = array(  CURLOPT_USERAGENT       => 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 Chrome/43.0.2357.65 Safari/537.36',

to:

$pfb['curl_defaults'] = array(  CURLOPT_USERAGENT       => 'curl',

edit /usr/local/pkg/pfblocker/pfblockerng_install.inc line 59:
from:

curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 Chrome/43.0.2357.65 Safari/537.36');

to:

curl_setopt($ch, CURLOPT_USERAGENT, 'curl');

-neo

P.s. @BBcan177 if you're going to fix this, while you're in there can you replace 1.1.1.1 with the RFC 5737 compliant 192.0.2.0 so we can use Cloudflare DNS w/o having to edit pfblockerng.inc and pfblockerng.sh please? :) (don't forget about the regex on pfblockerng.sh line 992)

Edit: BTW, not sure what's going on with caching, but restart php-fam didn't cause an update, I had to delete the /usr/local/pkg/pfblockerng/.pfblockerng.* files and then restart php-fam for the change to activate.

Edit2: diff for 2.1.4_17, fixes cloudflare DNS and Talos blacklists. pfblockerng_2.1.4_17.diff

scp/sftp the diff file to /usr/local/pkg/pfblockerng
run the following command from a shell:

cd /usr/local/pkg/pfblockerng ; patch -p0 < pfblockerng_2.1.4_17.diff

Thanks @neoaeon, after modifying the files the problem has been solved.

RonpfS

The feed now download without any modification to User agent.

Thanks for the update!

Looks like this feed is borked again. Worked fine for a while. Redid the useragent mods to fix.

Digital_ADHD

@provels updating useragent fixed this again for me

Zombie thread resurrection as this issue is back due to a regression.
