Minimal settings:
A certificate for bolt should be created:
" dbms.ssl.policy.bolt.allow_key_generation=true "
Trust everyone:
" dbms.ssl.policy.bolt.trust_all=true "
According to a warnig " dbms.ssl.policy.bolt.allow_key_generation " seems to be deprecated. The I did set certificates:
neo4j-home> ls certificates/bolt ie in " /etc/neo4j/certificates "
-r-------- ... private.key
-rw-r--r-- ... public.crt
drwxr-xr-x ... revoked
drwxr-xr-x ... trusted
GPG generation on 2020-12-08:
private.key = " 724186E93EF344AE "
public.crt = " FB4179C4F3D72FD883D107AE724186E93EF344AE "

Did you perhaps upgrade an old version of Neo4j without updating the config file to the new config files?
I guess because we don't support self signed certificates anymore this might fail now.
I suggest to install a let's encrypt certificate as explained here:
Wait a minute... neo 4.x does NOT support self signed certs for the bolt connection any more?!
For those of use using IP only for internal servers, LetsEncrypt will not issue bare IP certificates. What are we supposed to do now?!

It does but doesn't generate them automatically anymore.
Afaik you can generate them yourself if you want an encrypted connection.
And then use neo4j+ssc or bolt+ssc as protocol.
