Why can't I connect to my Minecraft server?

I'm trying to connect to my Minecraft server for the first time but I am unable to which frustrates me greatly.
I have added the Minecraft_Server.exe to the Firewall as public and I checked my computer's IP address in command prompt with the ipconfig command. When I enter the IP and the Port in 'Direct Connect' it does not let me connect.
When I check the server log, it says: [INFO] Disconnected /10.0.0.68:25565 Protocol Error.
What could be causing this issue and how can I resolve it?

Solution 1:

Are you hosting the server on the same machine as you're trying to play? You wouldn't want to connect to the IP; that won't work.

Assuming this is the case, try connecting to "127.0.0.1:25565", if 25565 is your port. This should work fine. You should also, if your firewall is set correctly, be allowed to connect to your computer's LAN IP (10.0.0.68:25565) from another machine on your network. Good luck!
