@pcabrera83 that particular issue you're experiencing might be the result of two things,

• A corrupt hosts file
• Another app running on the same port and even when it's closed it's not released.

Check if there's anything wrong with the said file, to see if it solves it.
Feel free to provide feedback so that we can close this issue or come up with a solution for your issue.

Where do I find the hosts file or check if another app is running on the same port?

@pcabrera83 see here for the hosts.
By default the hosts file should look something like this:

##
##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
##
127.0.0.1   localhost
255.255.255.255 broadcasthost
::1 localhost
fe80::1%lo0 localhost

I found it but my file is empty. Should I copy and paste what you have?

[pcabrera83]

Yep, that worked. I copied and pasted what you have and it seems to be working now.
Here is an article that covers this.

@pcabrera83 test it a little bit more and if the issue does not happen, feel free to close this issue and should any more arise, open a new one. Sounds good?
