Devise with Rails 4 and gmail smtp

Question

I have a Rails 4.1 app with Devise (confirmable). I am using gmail for sending mail. It was working fine for 8-9 months. But has suddenly stopped sending any mails, confirmation , forgot password or resend confirmation since April 1 this year. There was no change to any config file in my latest commits. There is no error message in console and it shows mail being sent. But no mail is delivered. What could be the problem? Is it to do with gmail? The full trace:

Actually, after some time gmail stops sending mails and requires login authentication, just login to the gmail account which you are using to send emails and it will start sending mails again! — Muhammad Ali, Apr 18 '16 at 11:30

Sorry for the trouble. I was doing something stupid. Was specifying my domain instead of "gmail.com" in the :domain settings for

`config.action_mailer.smtp_settings`

In you production.rb file active this:

config.action_mailer.raise_delivery_errors = true

Then you will start to see errors in the logs if something is happening when the emails are sent. Then you can make sense of what is the error.

Also gmail could be using Google 2-Step Verification which can block you system for sending email if it is not validated.

Thanks. Now I can see that I'm getting "EOFError in Devise". What does that mean. I am not using 2-Step verification There's nothing workable on Stack Overflow for that! – Sanjay Singh Apr 18 '16 at 13:49
No stack trace, I can't help you. Please some stack trace. – victor sosa Apr 18 '16 at 17:13
Ok. have added trace in original question. – Sanjay Singh Apr 18 '16 at 17:28
