How do I fix module update error “Error parsing metadescriptor, message='Could not download metadescriptor'”?
This article applies to all MetaDefender Core V4 and V5 releases deployed on Windows or Linux systems.
Cause: This error occurs when there is connection issue between MetaDefender Core and the update server, such proxy server not configured correctly, update server unreachable, or SSL issues.
Solution:
If MetaDefender Core is updating from the Internet:
- Make sure that update.dl.opswat.com is reachable from the MetaDefender Core server.
- If a proxy is used, please make sure it’s configured correctly in Proxy configuration.
If MetaDefender Core is managed by OPSWAT Central Management and is pulling module updates from OCM, to avoid SSL issue:
If OCM is using a certificate for HTTPS connection, make sure that the certificate subject’s common name matches the OCM server’s URL.
The OCM server’s certificate must also be trusted on the MetaDefender Core server by importing to the server’s trust store.
The OCM server’s address must be resolvable from the MetaDefender Core server.
