After re-issuing a LetsEncrypt certificate yesterday due to the Sept 30 broken cert problem, the certificate was working fine. However, after rebooting the server today, ECP/OWA and the management shell are not working. The event viewer showed:
An error occurred while using SSL configuration for endpoint 0.0.0.0:444. The error status code is contained within the returned data.
I found this article: https://martinsblog.dk/exchange-an-error-occurred-while-using-ssl-configuration-for-endpoint-0-0-0-0444/
I removed the port 444 cert entry by using the command: netsh http delete sslcert ipport=0.0.0.0:444
However, per the article I can't re-add the entry. When I try I get:
SSL Certificate add failed, Error: 1312
A specified logon session does not exist. It may already have been terminated.
Any assistance would be appreciated to figure out how to get Exchange working again.
