CentOS update on vagrant istall has consistent SHA1 errors on update

I have the most bizaar issue, on my desktop I am running the same version of Vagrant and Virtualbox (both the latest) as I am on my laptop.
On my desktop I can spin up a centos box and o an update with no problems, on my laptop is fails with SHA1 errors, it different files that error each time, but it happens every time. I have a feeling its either a network or a Virtualbox issue, just wondering if anyone else has seen this behaviour.
