Vagrant cannot forward the specified ports on this VM, since they would collide with some other application that is already listening on these ports.

I'm getting the above error and no answer I'm getting here or on stack overflow is helping. Reload isn't helping and neither is changing my ports on virtualbox unless I'm doing it wrong. Could I have a step by step answer that'd be easy for me to follow?
Here's the full error message:
"Vagrant cannot forward the specified ports on this VM, since they
would collide with some other application that is already listening
on these ports. The forwarded port to 8080 is already in use
on the host machine.

To fix this, modify your current project's Vagrantfile to use another
port. Example, where '1234' would be replaced by a unique host port:

config.vm.network :forwarded_port, guest: 8080, host: 1234

Sometimes, Vagrant will attempt to auto-correct this for you. In this
case, Vagrant was unable to. This is usually because the guest machine
is in a state which doesn't allow modifying port forwarding. You could
try 'vagrant reload' (equivalent of running a halt followed by an up)
so vagrant can attempt to auto-correct this upon booting. Be warned
that any unsaved work might be lost."
