Each time you attempt to login a new error code will generate if the reason for it persists, and also invalidate the previous ones.
The email verification is time sensitive meaning the verification link is only valid for x hours, so it is possible you got them too late, in which case you can only try again.
The code translate to failed email verification, I'm guessing you tried a couple times (it will block after x failed attempts). I have removed the block so you should now be able to login and ask for the verification email to be resent, hopefully you get it properly in time now.
