Amazon AWS Email Email Not Sending

I had email setup through amazon ses. Worked for 6 months. The last month the server hasn't been sending emails out using smpt. I get the following error message in the xenforo admin. I contacted amazon ses to make sure I didn't get suspended for some reason. They said everything is good on there end.

Code:

Server error log

  }
  ["_POST"] => array(0) {

}

Nothing has changed except for the common server updates. Does anyone have any ideas as to what is happened? Or can point me in the right direction to fix this?
