This usually happens when you connected to the internet via Wi-Fi instead of LAN

Wi-Fi has a 5GHz and 2.5GHz network - so if you are not able to use a cable, try the other GHz network option (happens with 2.5, fixed with 5)

Try my Modpack

I'm having the same error message repeatedly, but at random times. The biggest difference is that its my own server which I'm connecting to via the loopback address. I'm also connected to my router via cable and I have 1Gig speeds up and down.

How Can I Safely Play an Old Version of Minecraft?

Yeah, you can safely play Beta 1.7.3 using the official Minecraft Launcher. Just create a new installation, pick the old version from the list, and set a separate game directory so it won’t interfere with your current saves. The main compatibility issue is that old saves may break if opened in newer versions, so always back them up.

Mod for world Templates

No, there isn’t a dedicated Forge mod for world templates in 1.20.1. Your options are to use datapacks for custom worlds or run the Fabric mod through Connector.

How do I remove 3d headlayer on NPC's skin in CustomNpc? (1.16.5)

I do have to add that this is my answer for 1.12.2 but it should ALSO work for future versions.

I know this was posted almost 3 years ago but this is for anyone who is still looking for an answer.

First, find your config folder. -> C:\Users\ (desktop user's name) \curseforge(or the application where you've downloaded you mod)\minecraft\Instances\config (The config folder should be in the same folder as your mods folder.) Once you click on the config folder, search for CustomNpcs.cfg. Once found, click on it (you can edit it using notepad) and search for the line "headweartype". Set the value to 0 if you want a 2d head layer, set it to 1 for a 3d head layer. Then save the options and you should be good to go from there! :)
