Error: SuddenLink SMTP Server Not Working

What's Causing This Error

Since SendLink provides a GUI rather than a programmatic approach to set up SMTP, the one place where you may encounter errors is during authentication. However, you can sometimes experience this error due to a poor network connection.

Solution - Here's How To Resolve It

First, connect to SuddenLink using a fast, reliable internet connection.

Then, ensure to provide the correct SendLink username/password. If not, you can try resetting your SuddenLink password and setting up the SMTP connection again.

However, if none of the above works, try resetting the web browser cache or using a different web browser to access SuddenLink.
