can't bring up the Chef Web GUI in any web browser.

Hi,

After I have my Chef Server migrated from a physical-2-virtual machine, I can’t bring up the Chef Web GUI in any web browser.
We have Vagrant installed, but that we can’t bring it up. When I run ‘vagrant ssh’ it stops and timeout at SSH auth private key.
Do you think this error has anything with the migration from physical-2-virtual? If not, what else could it be, because I can’t execute ‘vagrant ssh’? When I run ‘vagrant ssh’ it says ssh_exchange_identication: read: Connection reset by peer. Could this be a firewall issue?

Any suggestions or ideas would really appreciate it!
