I've searched thru existing threads. I've enabled pop and imap in gmail settings and saved that. I've triple checked/copy pasted the right username/pass and the proper server etc is in there in gsa settings too. Logged in the same accounts manually copy pasting the same info so I know its right.
I tried turning on the 'allow less secure apps' thing as well.
I keep getting fails when testing, doing it on two separate, otherwise working manually, gmail accounts.
