Unable to update Fresh V14 install

We have a Virtualbox test environment, we built a new VM and installed FreePBX V14 x64 direct from a download taken Saturday morning at 8AM Eastern time. That file name was “SNG7-FPBX-64bit-1707-1.iso”

It installs without error and appears to be working normally. ?Able to access the CLI and GUI. Able to register phones.

We attempt to do module upgrades and it times out. We attempt to do a System update and it times out. We connect to the CLI and run a yum update. It errors with the following:

[[email protected] ~]# yum update
Loaded plugins: fastestmirror
Could not retrieve mirrorlist http://mirrorlist.sangoma.net/?release=7&arch=x86_64&repo=os&dist=$dist error was

Cannot find a valid baseurl for repo: sng-base/7/x86_64

We have a valid network with internet connectivity. DNS work properly as a ping to mirrorlist.sangoma.net yeilds consistent replies:
[[email protected] ~]# ping mirrorlist.sangoma.net

Not sure from where the error eliminates.

Bad install? Bad environment?

Any thoughts greatly appreciated.
