Vagrant box: default: Warning: Connection timeout. Retrying

I'm having trouble getting vagrant box running. I tried the solution in this thread: Vagrant stuck connection timeout retrying. No luck there. I also tried increasing the value of config.vm.boot_timeout. No luck either. Please help! ``` $ vagrant destroy && vagrant up default: Are you sure you want to destroy the 'default' VM?

This means that Vagrant was unable to communicate with the guest machine within the configured ("config.vm.boot_timeout" value) time period. If you look above, you should be able to see the error(s) that Vagrant had when attempting to connect to the machine. These errors are usually good hints as to what may be wrong. If you're using a custom box, make sure that networking is properly working and you're able to connect to the machine. It is a common problem that networking isn't setup properly in these boxes. Verify that authentication configurations are also setup properly, as well. If the box appears to be booting properly, you may want to increase the timeout ("config.vm.boot_timeout") value. ``` Thanks in advance!
