One of my email addresses stopped receiving/sending emails over the weekend. I have everything from Friday, but nothing since then. I also cannot get an email to send. My other gmail account is working fine. I know that the troublesome email address is working and is not a problem with my domain server since I am receiving/sending on my phone. Just my laptop with Mail is not working. I am running  Version 17.7922.42017.0

I've been running this email address on this laptop for about 3 months & it has worked fine.
