What are your settings? I can get into my gmail with no issues. see screenshots

I can look at the settings but I don't know how to get them to you. I just tried to login again to my google account and it logged me in with no problem. Nothing has changed from an hour ago when it would not work.

Use the snipping tool to make screenshots. You're logged in, issue resolved?

The problem is intermittent. That is the confusing part. I have gmail in my favorites and use that to get to the mail account. My wife suggests that I get rid of the shortcut and clear history and then get to gmail by typing in the name each time. I am trying that now.
