Describe the bug
ive seen a few people have had this issue but not seen a fix

ive just started a new server with a few friend using the origination mod pack, upon attempting to use cosmetica it says "we couldn't authenticate your account! this could be because your using a cracked Minecraft account or your internet isn't working"
