Your connecting client rejected the certificate that the server offered. Most likely that is because the certificate is invalid or expired. You should check the certificates on your server and check why they are not getting renewed.
Thanks for the reply...I got it fixed. I followed the example from. https://www.howtoforge.com/securing...server-with-a-valid-lets-encrypt-certificate/ so I went back and retraced the steps and fixed it.
