AWS amazon SES stopped working suddenly
As a quick suggestion, check the SES time by making an HTTP request to SES (e.g. wget -S "https://email.us-east-1.amazonaws.com"), and compare to your server's time. Update the server's time (or use NTP if you aren't already) and see if the problem resolves itself.Thanks @cyberx86.
As experts suggested:-Britain (and probably other countries) switched over to winter time at the same day your error started happening and the error says that the time is more than 300 seconds wrong. I would vote for that being the root cause
The one reason I can think for this is difference in the time between amazon mail server and your server.
Do the followings
1) Get the amazon mail server time
wget -S "https://email.us-east-1.amazonaws.com"
2) Get the your server time
wget -S "http://yourdomain.com"
If there is a time diffrence of more than 300 seconds, change your server time3) sudo date nnddhhmmyyyy.ss WHERE
