Unable to download new iocage releases via iocage fetch

When using iocage fetch to grab new releases (so I can upgrade my v11.2-U7 Jails), I am getting the following error:

It seems I am unable to connect to download.freebsd.org, as per the following thread on the forums:

https://www.ixsystems.com/community/threads/issue-getting-jail-releases.80642/#post-558752

I am UK based with Sky as my ISP - using a VPN (NordVPN) from my PC I can connect to the above site via France/Spain, but not UK (and Norway) for some reason - I just randomly selected counties to try.

I am also getting the same error when trying to create a Jail with the UI.

I'm not sure if this a ISP issue or freebsd issue - but the error does need to be caught and managed by FreeNAS instead of failing.
