Curl calls used to download Live Update files will fail if using a proxy.host with an IPv6 address that does not include brackets.
Live Update necessitates an IPv6 proxy.host have brackets, while IP Reputation necessitates that it does not have brackets. This discrepancy results in one or the other continually failing when attempting to use an IPv6 proxy.host.
Live Update is configured through a proxy.host that is using IPv6 and does not include brackets around the IPv6 value. E.g. "[IPv6]"
If possible, utilize a proxy.host value that is not an IPv6 Address.
None
