Hi,
I have a neo4j v4.4 DBMS running on a Windows 10 machine and access it from a WSL instance via the IP 172.31.240.1 with no problem. I have now created a version 5.7 database and have configured, similarly to the v4 one, dbms.default_listen_address=0.0.0.0, so that Neo4J accepts the request from the WSL VM. Using the same code as before, I cannot establish a connection. I have tried telnet 172.31.240.1 7687 which works with the v4 DBMS but fails to connect with the v5 one. Is there any additional settings I need to change in order to be able to connect with version 5.7?
@boulanger
conf/neo4j.conf settings are newly named in v5 compared to v4. See Changes to configuration settings in Neo4j v5 - Upgrade and Migration Guide
Whereas v4 is named dbms.default_listen_address the equivalent v5 is server.default_listen_address
note this is but one change. there are many more
Hi @dana_canzano , thank you for your message! Sorry I was unclear, I did use the new v5 settings name server.default_listen_address=0.0.0.0 since one only needs to uncomment the line in the settings. But it still does not connect and I wonder if there is anything else I need to tweak in order for the Neo4J server to listen to my requests coming from a subnet (it works in v4 without any further changes except the dbms.default_listen_address=0.0.0.0 config).
I wonder if the following log entries are indicative of something:

Also, in security.log, I have this:

But this seems unrelated because I cannot even connect.
