Laravel/Homestead Invalid IP Address

I am using Laravel 6.2, Vagrant 2.2.6 and VirtualBox 5.2. Followed the tutorial for Homestead setup. But when I visited myapp.local (out of the box without modifying any code), I got the following error message:

NotFoundHttpException in RouteCollection.php line 161

(Please see my comment below explaining why I was getting this error)

Mistakenly, I modified the ip address in my Homestead.yaml file and now, no matter what I do, I am getting the following error message.

Network settings specified in your Vagrantfile define an invalid
IP address. Please review the error message below and update your
Vagrantfile network settings:

  Address: 192.168.10:10
  Netmask:

Example:

machine1234:Homestead my_user_name$ vagrant destroy

Homestead.yaml looks like this:

Any idea on how I can fix this issue?

Your IP address has a colon!

Change:

  Address: 192.168.10:10

To:

  Address: 192.168.10.10
