Hey Walter,

It's sitting behind:  DDoS protection by Cloudflare
So it makes sense that you would not be able to download it using wget.
The only option probably is using a web browser.
I would suggest contacting clamav.net web/system admins to verify what are the options.

All The Bests,
Eliezer

Hello,

can someone test the following URL

http://db.local.clamav.net/daily-26102.cdiff

e.g.   wget http://db.local.clamav.net/daily-26102.cdiff

I have an older squid (v3.1) there this works,
but with the newer ones (v3.4 and v3.5) this doesn't;

is there an explanation why?

the log shows this:

client-ip - - [10/Mar/2021:06:43:50 +0100] "GET 
http://db.local.clamav.net/daily-26102.cdiff HTTP/1.0" 503 8645 "-" 
"Wget/1.12 (linux-gnu)" TCP_MISS:HIER_DIRECT

the suspicious thing: when using a browser: this works with any squid, 
but this doesn't help because the clamav signature updates are loaded
by the freshclam which shows the  same failure as e.g. wget

client-ip - - [09/Mar/2021:06:00:03 +0100] "GET 
http://db.local.clamav.net/daily-26102.cdiff HTTP/1.0" 503 8642 "-" 
"ClamAV/0.103.1 (OS: linux-gnu, ARCH: x86_64, CPU: x86_64)" 
TCP_MISS:HIER_DIRECT

I noticed this two days after the nightly freshclam (signature update) 
failure,
and changed the freshclam config to use the squid v3.1;

Thanks,
Walter
