Hi MikymeoTwitch2155,
If you're seeing that connection failed message, you'll want to first make sure your Encryption Key is the same on both computers (Security tab -> Change encryption key). You can also double check your computer name and IP address are correct.
If the above things are correct, a common issue would stem from firewall port settings. The link below documents how you can test if that's the case and then resolve with an included batch file.
Please let us know if this helps and if you have any other questions.
Best regards,
