HTTPS SSL CA cert expired. Steps to take to renew? Please help!

[S_ Toyo]

I tried following this guide:

https://confluence.atlassian.com/bitbucketserver0514/administering-bitbucket-server/proxying-and-securing-bitbucket-server/securing-bitbucket-server-with-tomcat-using-ssl

Another post I found said I wouldn't have to start from scratch each time. And that I would just be able to run the following command to generate a new .CSR that I submit to CertSrv on my domain controller server. But I don't get a. csr file so not sure what I'm doing wrong. This is my FIRST time trying to do this. I did not create the original keystore FYI.

"%JAVA_HOME%\bin\keytool" -certreq -keyalg RSA -alias tomcat -file certreq.csr -keystore C:\Atlassian\applicationdata\bitbucket\shared\config\ssl-keystore

This is what I ran and nothing happened. It didn't give me a file or anything.
