Thank you for your helpful replies.
However, when starting server I receive following error

2020-07-06 16:54:25.162+0000 INFO Neo4j Server shutdown initiated by request
Server fails to start when line dbms.connector.bolt.tls_level=OPTIONAL is uncommented.
If I am not mistaken it is related to io/netty/internal/tcnative/SSLPrivateKeyMethod
I spent much time trying to figure out what is the problem and I have no clue how to proceed anymore.
I kindly ask you for help.
I am using neo4j 4.1.0 Enterprise
I generated self-signed certificate with command:
openssl req \
-newkey rsa:2048 -nodes -keyout private.key \
-x509 -days 365 -out public.crt
certificate folder structure is following
└── default
├── private.key
├── public.crt
├── revoked
└── trusted
plugins are following:
netty-all-4.1.50.Final-sources.jar
netty-all-4.1.50.Final.jar
My configuration neo4j.conf is following:
