Laravel Swiftmailer, email is not working on Azure

Question

My site emailing was working fine on ubuntu. It stopped working after moving to Azure cloud server. I am using gmail smtp and getting the following error:

Swift_TransportException in AbstractSmtpTransport.php line 383:
Expected response code 250 but got code "535", with message "535-5.7.8 Username and Password not accepted. Learn more at
535 5.7.8 https://support.google.com/mail/?p=BadCredentials m143sm21528218qke.18 - gsmtp
"

Any sort of help is appreciated.

Answer 1

Based on the message above, the error might be due to the mismatching of password with account. You can check it first. If it doesn't help, I have no idea either.

Answer 2

If user and pass are correct then Step 2 might help https://support.google.com/mail/answer/7126229?p=BadCredentials

Step 2: Try these troubleshooting steps

Update your email client to the latest version.

Use an App Password: If you use 2-Step Verification, try signing in with an App Password.

Allow less secure apps: If you don't use 2-Step Verification, you might need to allow less secure apps to access your account.

If you recently changed your Gmail password, you might need to re-enter your Gmail account information or completely repeat your Gmail account setup on your other email client.
