mailersend.com smtp error

[bsnsagency]

What does this error means when trying to connect smtp (mailersend.com)?

• Failed to authenticate on SMTP server with username "MS_uY4Nyi@licente24.live" using the following authenticators: "LOGIN", "PLAIN". Authenticator "LOGIN" returned "Expected response code "235" but got code "535", with message "535 Authentication failed.".". Authenticator "PLAIN" returned "Expected response code "235" but got code "535", with message "535 Authentication failed.".".

If this does not apply https://www.mailwizz.com/kb/failed-...username-xyz-using-2-possible-authenticators/ then you might want to double check the access credentials and the smtp server logs to see what exactly fails.

Another example:

I changed from swiftmailer to symfony as adviced and i get this error on Amazon SES API:

• Error executing "CreateTopic" on "https://sns.us-east-2.amazonaws.com"; AWS HTTP error: Client error: `POST https://sns.us-east-2.amazonaws.com` resulted in a `400 Bad Request` response:

Attributes Reason: Topic already exists with different attributes

I think you need to remove the SNS Topic from AWS and try again.
