The handshake failed due to an unexpected packet format???

[lordie7]

So iv been trying to use a modpack from curseforge and everytime iv tried to install a pack it says 'the handshake failed due to an unexpected packet format' iv looked everywhere online to figure out the problem and not one site has anything on it and not even curseforge has a fix for it and im at a loss on what to do.. i tried uninstalling forge i tried deleting my minecraft folder in curseforge and still did not work i even tried a different account on my computer just to get the same result!!! im at a loss and im not sure what to do. any help would be amazing thanks for reading.Insert image from URL

Your question contains no useful information, not even the name of the mod pack.

But this support forum is for forge.

Curseforge help can be found here:

Sorry my bad i meant to say that it says the error for all the modpacks i try to download its not a specific modpack thats the issue its with everyone i try to install and i tried to find support on the curseforge form and still could not find a single thing about the issue
