iMessage not working on brand new MBA

[itsaustinh]

I just recently got my first Mac, the MBA 13" 😀 For the first few days iMessage worked perfectly on my Mac and all my other devices, but since yesterday all of the messages I try to send get the red exclamation point saying it could not be sent. I'm not receiving messages either. I signed out of the account on iMessage and signed back in and I am still getting the same error. Does anyone know what could be going wrong?

Go into iMessages app and go to it's Preferences, Accounts and what accounts are you using (don't list the email address, just tell us if is a iCloud account, Google account or Yahoo, AOL or lastly an ISP account) what accounts in the application.?
