Upgrade pfSense using a repository proxy (Nexus OSS) problem

[luckybuilding]

Hi all,
I have used Nexus OSS for updating and upgrading pfSense in lower versions. However, it seems that version 2.7.0 uses other URLs for the repository, and it fails to update using the old method!

It seems that the version uses some NetGate addresses for this!

Does somebody know about these details helping me fix this?

Thanks
