Hello,

Trying to install and configure nexusVersion=“3.32.0” on centos 9 and redhat 9. And came accross the following error:  
Failed to start  
java.nio.file.AccessDeniedException: /opt/sonatype/nexus/etc/ssl/keystore.jks

The same installation works fine on centos 7.9.

Noticed that openssl versions are different:  
OpenSSL 1.0.2k-fips for centos 7.9  
and OpenSSL 3.0.7 for Centos 9.

Also used the certs and keystore, created on 7.9, on centos 9 (used the same host name for both servers) and nexus WORKED.

So is there anything I need to do for it to work on centos 9 and redhat9?  
Thank you. Any advice would be highly appreciated.
