Credentials are correct, i am able to login in the site.

Hi Snehan,
In your case it is seen that you are using a Gmail SMTP server, Google sometimes does not let you login because it has flagged this sort of login as “less secure”, so what you need to do is go to this link while you’re logged in to your Google account, and allow the access:
https://www.google.com/settings/security/lesssecureapps

Hey Snehan,

I have faced the same issue while configuring the Gmail SMTP, but I’m able to do it by enabling the CAPTCHA for the Gmail account. Refer to the below URL to unlock the CAPTCHA.

Hey Snehan,
I had faced the same issue while configuring the GMail SMTP,
I followed these two steps and was able to configure my smtp server:

  1. Allow access to less secure apps
    https://www.google.com/settings/security/lesssecureapps
  2. Enabling the captcha before clicking on the save SMTP config
    https://www.google.com/accounts/DisplayUnlockCaptcha
