Mail doesn't connect to Gmail accounts

[Foxer]

Pretty straightforward. Since installing the PB, the new mail hasn't connected to any of my google managed mail accounts. It gets stuff from .mac fine, but not gmail. Just shows the "not connected" icon, but nothing I can do will compel it to connect. This is a big enough deal to revert back to Mavericks, so I hope there is an easy fix.

I had this issue -

Mac 1
- Gmail Account 1: Everything migrated fine
- Gmail Account 2: Had to delete and readd it again

Mac 2
- Gmail Account 1: Everything migrated fine
- Gmail Account 2: Had to delete and readd it again, also had to reset the login keychain because the settings in "Internet Accounts" couldn't access Gmail. Could access it fine in Safari though

This happened to me too. It was working fine one day, then the next my gmail account wouldn't connect through anything (mail, messages...) but I could login fine through safari, and there seemed to be no issue in 'internet accounts'. I was one step away from deleting and re-adding, but I reset my gmail password and everything started working again.
