Authentication Failure

I am having problems using my alias account which is ***@cox.net through my gmail. It worked perfectly for the last couple of years and then just stopped. I get this message: "Delivery incomplete. There was a temporary problem delivering your message to ....The response from the remote server was:454 4.7.0 ... authentication failure : try again later". 

So I deleted the "send as" email address in my gmail settings and then tried to add it back to see if that helped. Now I can't even do that. I keep getting this message. 
Authentication failed. Please check your username/password.
Server returned error: "454 4.7.0 ... authentication failure : try again later code(454) "

I've read a lot of these posts and I think I have really tried everything. My password is correct (yes, I've used it to sign in at Cox.net) and I've tried my user name with and without the @cox.net.  "smtp.cox.net" is correct and I've tried both SSL 465 and TLS 587. As per another of these posts I've tried doing it through an incognito window.

I really need help, please!!! Thanks.

    Thanks for confirming you can sign into cox.com. Are you able to send and receive email from our myemail.cox.net website? Also, https://www.cox.com/residential/support/imap-server-settings.html is a link to our website with the IMAP server information.

    I'm trying to add my Cox email as an alias in gmail.  I get the same error.  Cox webmail works fine.  I'm using the right password.  I've tried "smtp.cox.net" and "smtp.west.cox.net".
