+## Troubleshooting
+
+If you have issues installing ssh tunnel to the environment, try adding `:nfs_udp => false` to `override.vm.synced_folder` options in the `Vagrantfile`.

<p>I'm not sure how whether NFS is using UDP or TCP (which I assume is the result of changing that) has anything to do with ssh tunnels?</p>
