Scope

FortiSIEM collector.

Solution

Issue:

FortiSIEM collector upgrade to version 7.5.1 fails with the following error observed in upgrade logs (/usr/local/upgrade/logs/ansible.log):

msg: Failed to download metadata for repo 'security': Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried
