Channels are not automatically synchronized in SUSE Manager.

This document (000021194) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Manager Server 4.3.x

Situation

In the SUSE Manager Web UI: Admin -> Task Schedules -> mgr-sync-refresh-bunch shows mgr-sync-refresh as FAILED.

No entries are logged in /var/log/rhn/reposync.log

In /var/log/rhn/rhn_taskomatic_daemon.log, [DefaultQuartzScheduler_Worker-20] ERROR com.redhat.rhn.manager.content.ContentSyncManager - accessibleUrl: pointing to URLs other then updates.suse.com are being logged.

Example from /var/log/rhn/rhn_taskomatic_daemon.log

2023-08-17 01:27:30,308 [DefaultQuartzScheduler_Worker-20] ERROR com.redhat.rhn.manager.content.ContentSyncManager - accessibleUrl: http://download.nvidia.com/suse/sle12sp3/repodata/repomd.xml IOException Read timed out
2023-08-17 01:27:39,220 [DefaultQuartzScheduler_Worker-20] ERROR com.redhat.rhn.manager.content.ContentSyncManager - accessibleUrl: https://download.nvidia.com/suse/sle15/repodata/repomd.xml IOException Connect to download.nvidia.com:443 [download.nvidia.com/192.229.220.191, download.nvidia.com/2606:2800:233:1b35:1195:10b9:2466:6a8] failed: Network is unreachable (connect failed)

Resolution

Whitelist the URLs found in the /var/log/rhn/rhn_taskomatic_daemon.log to which ERROR com.redhat.rhn.manager.content.ContentSyncManager - accessibleUrl: are logged.

Cause

The network setup was changed to be more restrictive, but only updates.suse.com was added to the whitelist of the proxy server.

Additional Information

Apart from regular SUSE products, SUSE Manager offers channels/products for which it needs access to other URLs than updates.suse.com.
