We’ve used your plugin faithfully for the last 1.5 years. At the beginning of November we ran into a problem with it. We use Amazon SES to send although we’ve tried Sendgrid given the recent issue and it throws the same error. Whenever trying to send or test a newsletter we get this error
SMTP -> ERROR: Failed to connect to server: Connection timed out (110)SMTP connect() failed.
It’s simple, you provider is blocking the connections to external services. You should ask the provider to unlock the SMTP ports you’re using to connect externally.
