World host protocol error still doesn't fixed

[Cyber147115]

Hello, its me again.
I did what you said, restart the game and launcher, but unfortunately it doesn't solving the issue i got. In one day when i start the game i saw its connected, but after few days again went into the error i posted week ago (probably). Maybe there's alternate methods how to fix this? Or this cannot be fixed no matter what i do?

Are you able to connect to standard Minecraft servers now? If you cannot, this is not a bug with World Host. World Host uses the same verification mechanism as Minecraft servers do, and if you cannot authenticate with Mojang, World Host has nothing to do other than assume you're trying to pretend to be another player.

Still cannot connect servers, maybe I didn't tell you but I'm using unofficial Minecraft launcher. Maybe due to the launcher I using world host giving this error?

What launcher are you using? And can you try without any other mods?

[Cyber147115]

I using Legacy Launcher (as how my friend recommended). And World host mod still giving error, even without any other mods. Previous month it worked before (with other mods (we were playing on Forge version with OptiFine mod separately)).

I can also send screenshot with other mods listed if it's required to see

World Host did not used to perform any kind of user verification. Try signing out and signing back in.

Signing out and signing back in didn't help.
