While attempting to start Kerio Connect Antivirus and Anti-spam, the modules are facing issues generating the following errors:
AntivirusModule.cpp: Antivirus update failed: Cannot find update location: The
requested URL returned error: 407. Download failed.
BitDefenderAntispamClient.cpp: Unable to initialize Kerio Anti-spam plugin, error:
Kerio Anti-spam plugin cannot update: Unable to fetch updates: CouldNotLogin
SpamClientBase.cpp: Server: Kerio Anti-spam plugin cannot be initialized: Kerio
Anti-spam plugin cannot update: Unable to fetch updates: CouldNotLogin (-2103).
Administrator access to Kerio Connect server
The Antivirus and Anti-spam plugins cannot find the updates' server and cannot proceed with downloading the necessary packages. There is a middleware device or software in between Kerio Connect local server and Kerio Connect main server which supply the Antivirus Database definition updates. Common devices/software include proxy servers configured in Kerio Connect Webadmin, firewalls, 3-rd party Antivirus software enabled on local Kerio Connect installation.
- Make sure that the Antivirus Exclusions for Kerio Connect are in place
- Login to Kerio Connect Administration -> Configuration -> Advanced Options -> HTTP Proxy tab -> make sure the proxy configuration is disabled.
- Check the HTTPS connection (port 443) between your Kerio Connect server and Kerio updates servers. You should see the following.
Important: if the connection is blocked, the webpages will return Connection Timeout responses or similar.
Note: if you have Kerio Control as the firewall, for more information please refer to configure the firewall to allow Kerio Connect services.
- Make sure necessary Kerio Connect folders are excluded from the 3-rd party Antivirus scanning. For more information, please refer to Antivirus Exclusions for Kerio Connect.
The Antivirus and Anti-spam modules are functioning properly, no errors reported in the logs.
