Unable to Receive Mail

I cannot receive Cox email, it started last night (8-11-21) and still exists this morning, Is this a Cox problem or a Me problem?  The error message that I get says the following.

There may be a problem with the mail server or network. Verify the settings for account “Cox” or try again.  The server returned the error: An SSL error has occurred and a secure connection to the server cannot be made.

I can send emails.

Thanks
