No problem — you don't need to paste anything. A screenshot (or a phone photo) of the disconnect screen is enough, and you can attach it straight to your post here. If you can reach the file, attach latest.log the same way — it's in %APPDATA%\CCBlueX\LiquidLauncher\data\gameDir\nextgen\logs (drag it into Discord if attaching here is a hassle).
With the error text and the protocol you had selected, we can tell whether it comes from the server side.
