Failed to start SASL connection

I'm on Yosemite 10.10.3. I've been getting these errors recorded in my log. Where do I start looking and how do I go about fixing it? I only know it has something to do with my Gmail accounts in Mail...

If you aren't having any problems with the computer or your Gmail accounts in Mail, just ignore it. If you are having problems, please post them. My Console application is full of error messages.

I tried that (unchecking "Automatically detect and maintain..." for both, IMAP and SMTP). Once I woke the MBP onto a new network from sleep, and started Mail, my logs filled with the SOSCCThisDeviceIsInCircle messages. Worse, my trick of stopping Mail and starting it again didn't even work when the auto detect was unchecked. I'd be interested in your experience, if it works for you across multiple Mail starts on new networks.

Hello, YasonX!

Now i write this post from another network and now my console Mail messages still clear, no SOSCCThisDeviceIsInCircle or any strange error messages.

I'm also do it on MBP, and now i tried disable/enabled Gmail account, restart Mail app, but console is still clear and "Automatically detect and maintain..." has unchecking state.

But i'm unchecking both "Automatically detect and maintain..." settings just yesterday, so i think time for one day is not enough time to test this from your problem.

Otherways, may be you network provider has own some specific settings of Gmail.

Hi AlexS2,

The unsetting of "automatically detect..." setting did never work for me. However, after upgrading to 10.10.4 I don't have this particular Mail problem with GMail any more. Mail now chats nicely with GMail.

Regrettably, after upgrading to 10.10.4 I still see: Failed to start the SASL connection

With the 10.10.4 update, the rules of the game have changed all.

Try this: Using your browser, sign onto your Gmail account. You will be taken through the steps for 2-step verification and given a new password. Follow the instructions, and things may start to work correctly. It did for me. Now I get some other bizarre messages, but that is neither here nor there.

Same here. After update to 10.10.4 and rechecked "Automatically detect and maintain..." not a single error message in any of the five gmail accounts.

With Yosemite 10.10.4 you now want to check this box!
