Hello Mark, Thank you for the heads up. The SSL connection is only used to redirect to the non-SSL version of the site. However, this redirection still requires a valid SSL certificate. This issue has been fixed. Please also see http://logback.qos.ch/redirect.html Best regards, On 23.03.2020 11:21, Mark Carroll wrote:

I'm guessing it is known that the webserver TLS certificates for https://logback.qos.ch/ and https://www.slf4j.org/ expired last week? Apologies if I missed the mailing list traffic or bug report for it or if this is the wrong place to mention the issue.
