None of the categories describe my problem so sorry.
Modpack/Launcher: FTB Infinity Evolved
Using a MacBook Pro with macOS Mojave Version 10.14.2
I’m having issues logging into my Minecraft account on the FTB profile so I can go join a server. I know my email and password are 100% correct, I used it to log into Mojang.com, minecraft.net and the regular Minecraft launcher just now.
However when I go into create a profile, put it my email and password and then hit launch on Infinity Evolved, I get this popup error:
"Invalid username or password!
- Check your username or password. If you use OLD non-migrated account try using username instead of email.
- You need to use paid minecraft credentials. Mojang account without paid MC won’t work."
And I get this console error:
"Invalid credentials recieved for user: (my email):
com.mojang.authlib.exceptions.InvalidCredentialsException: Invalid username format. Username must have between 4 and 16 and alphanumeric characters. Underscore is allowed."
My account is migrated so I know its uses email. I have certainly paid for Minecraft as I can get onto any server in vanilla Minecraft. I’m not sure why the its asking between 4 - 16 characters when it says Username/Email. I’m thoroughly confused and just want to play a modpack on a server with my friends.
Update: I just tried creating a profile using a friends account that he just launched with and I got the same error message, even though the email and password are correct and he was able to launch.
