SMTP Configuration Issues with smtppro.zoho.com: Authentication Failures and Connection Closures Despite Correct Credentials

SMTP Configuration Issues with smtppro.zoho.com: Authentication Failures and Connection Closures Despite Correct Credentials

Hi there,

I am the email administrator of studyx.ai. In the SMTP Server Settings on chargebee.com, I have configured the SMTP server address as smtppro.zoho.com and the SSL port as 465. While attempting to set up different email accounts with their respective passwords, I encountered three scenarios:
  1. Successful setup;
  2. Connection closed/reset by your SMTP server smtppro.zoho.com;
  3. Authentication Failure. Please check your SMTP credentials.

I am confident that all the passwords I attempted are correct, as they all allow normal login at https://accounts.zoho.com/signin.

May I ask what is causing this issue and how should I go about resolving it?


Regards,

Xiang
