When using with Amazon AWS EC2 or Lightsail, suddenly reminder stopped sending emails.
The log is:
Traceback (most recent call last):
File "/home/ubuntu/reminder/reminder.py", line 57, in <module>
server = smtplib.SMTP(host)
File "/usr/lib/python3.6/smtplib.py", line 251, in __init__
(code, msg) = self.connect(host, port)
File "/usr/lib/python3.6/smtplib.py", line 336, in connect
self.sock = self._get_socket(host, port, self.timeout)
File "/usr/lib/python3.6/smtplib.py", line 307, in _get_socket
self.source_address)
File "/usr/lib/python3.6/socket.py", line 724, in create_connection
raise err
File "/usr/lib/python3.6/socket.py", line 713, in create_connection
sock.connect(sa)
TimeoutError: [Errno 110] Connection timed out
It looks like somewhere between 26/01/20 and 01/02/20 Amazon improved their firewall? and the connection sequence previously used between EC2 / Lightsail and Amazon SES no longer works.
It works from outside AWS though.
