There could be a large number of reasons for this. It looks like Gmail can't communicate with the outside world due to a port issue. Gmail usually travels via port 587, 465, or 25; all which are standard ports are are generally not blocked by firewalls. That's what firewalls do, they block ports.

First try simply quitting all open applications, turning off your computer then back on. If that doesn't resolve it, next go to system preferences: security and privacy: Firewall. Make sure Firewall is turned off…

Most likely that's not the issue but good to check anyway. Next, the issue could be that a firewall has been turned on on your modem/router given to you by your ISP. This is unlikely and a little more technical than you might want to get into so I won't describe that process.

Before continuing it would be very helpful to have a few answers to other questions:

Does the email continue to run fine on your phone/ipad/other computers in the house?
Can you use a different wifi network to see if the problem goes away?

There is a setting at gmail.com that may be preventing the issue also. Gmail has a way of blocking untrusted applications. Apple's Mail is one of those untrusted applications. I can help you with that but would need your gmail password to log on to your account to look at those settings.
