Hi, I upgraded stunnel from version 5.44 to 5.56. But now I'm getting the following error : CERT: Pre-verification error: unsupported certificate purpose Rejected by CERT Setting verifiy to 0 slove temporary the issue but is not secure at all. As testing pupose, I recreated new certificate with the following command but ending with the same issue: openssl req -new -x509 -days 365 -nodes -config stunnel.cnf -out stunnel.pem -keyout stunnel.pem How to fix this ? Thanks for you help, André.
