Messages on Macbook Pro Disconnected
I have a brand new 13" Macbook Pro with El Capitan. I use "Messages" to send iMessages to my family from this Macbook. For some reason, Messages suddenly stopped working. It says "Disconnected" in the lower left corner. If I try to log in, it says "Connecting..." just briefly, then switches back to "Disconnected."
I had changed some settings in my iPhone 6+, and thought maybe I checked something by accident that caused the disconnection. However, when I go to Settings > Messages > Text Message Forwarding, the switch next to my Macbook Pro is green. I even tried switching it off and re-pairing it (where you have to re-enter the code from the computer on the phone). No luck.
Can you recommend anything else to try that might clear up this "Disconnected" issue with Messages? Thank you for your time.
MacBook Pro with Retina display, OS X El Capitan (10.11.3)
