Gmail accounts are offline
Have Sierra 10.12.14 on a late-2016 MBP with Touch Bar (which also stopped functioning). All of a sudden my gmail accounts are offline. I keep getting messages for my password, then nothing happens. Took a screenshot of my mail settings, and they look okay, but when I go into Mail, there is no smtp or port showing. Thanks.
