Re: Upgrade Error

J,

Did it work for you eventually?

I don't see this message in your log "Please provide the following cf-ray id with your ticket: ..."
That makes me wonder if you were blocked by Cloudflare or by a different firewall.

Another idea worth testing if it still isn't working -- you could delete the "freshclam.dat" file from the install "database" directory and then run freshclam.exe again to see if that resolves it.

Best,
Val

Subject: [clamav-users] Upgrade Error

I am attempting to upgrade from 0.103 to either 1.4.3 or 1.5.0 and received the following error on both versions;

ClamAV update process started at Wed Oct 01 14:22:29 2025

daily database available for update (local version: 27777, remote version: 27779)
Current database is 2 versions behind.
Downloading database patch # 27778...
WARNING: downloadPatch: Can't download daily-27778.cdiff from https://database.clamav.net/daily-27778.cdiff
WARNING: Can't download daily.cvd from https://database.clamav.net/daily.cvd
WARNING: FreshClam received error code 403 from the ClamAV Content Delivery Network (CDN).
This could mean several things:
 1. You are running an out-of-date version of ClamAV / FreshClam.
    Ensure you are the most updated version by visiting https://www.clamav.net/downloads
 2. Your network is explicitly denied by the FreshClam CDN.
    In order to rectify this please check that you are:
   a. Running an up-to-date version of FreshClam
   b. Running FreshClam no more than once an hour
   c. If you have checked (a) and (b), please open a ticket at
      https://bugzilla.clamav.net under the 'Mirrors' component
      and we will investigate why your network is blocked.
ERROR: Database update process failed: Forbidden; Blocked by CDN
ERROR: Update failed.

     I'm running Windows10.                Thank you
