Is there a way to connect to an Open To Lan World without a connection to Mojang/Minecraft?

Solution 1:

After spending some time looking up certain how to find my way around having to connect to Mojang servers I reached a solution.

Instead of using the Open To Lan option I decided to use a server that runs off my computer. I downloaded the server files from the Minecraft website for servers here. And then after following the instructions on how to setup a Minecraft server from Servermania managed to have it setup.

The only thing I had to do then was change offline mode to false in server properties (after receiving multiple warnings not to do this. Which makes sense but I was rather desperate) and reap my rewards. Just tell the other players who you want to join your ip adress and the port and let them join. Obviously skins won't work but that's fine for all I care.

Obviously you have to have a rather decent PC to manage the server but it worked out in the end.

Side note: To become operator in your server replace the two brackets in your ops.json file with

[
  {
    "uuid": "YOUR-UUID",
    "name": "YOUR-MC-USERNAME",
    "level": 4,
    "bypassesPlayerLimit": true //(or false here depending on what you want)
  }
]
