SSL Certificate Renewal Issue

Question

Hello,

We need to renew our SSL certificate.

I executed the following command:

openssl req -nodes -new -newkey rsa:2048 -sha256 -keyout 'mdm.domaine.fr.key' -out 'mdm.domaine.fr.csr' -subj '/CN=mdm.domaine.fr' -utf8

This generated two files:

• mdm.domaine.fr.csr
• mdm.domaine.fr.key

I then placed the certificate file provided by our hosting provider (mdm.domaine.fr.crt) into the following directory:
/var/lib/tomcat9/ssl/

However, I am unable to complete the certificate renewal process.

Could you help me identify the cause of the issue or guide me through the steps to verify?

Thank you in advance for your support.

Best regards,

Tomcat uses a proprietary key format "JKS" (Java Key Store).
