I have been using Neo4j on a ubuntu server for months, but I downloaded the dependencies for apoc.mongodb a few days ago, then restarted Neo4j following the instructions [here](https://neo4j.com/labs/apoc/4.2/overview/apoc.mongodb/apoc.mongodb.first/). I no longer can connect to Neo4j since I did this! I tried the browser and the shell. In both cases, I get "connection refused". The configuration file is the same, and nothing changed at all. I can't find any explanation for this!
Here is some detailed info that may be needed:
Neo4j version: 4.4.4 The command to restart neo4j: sudo systemctl restart neo4j.service The network configurations: dbms.default\_listen\_address= (I also tried 0.0.0.0)
Bolt connector:
dbms.connector.bolt.enabled=true
dbms.connector.bolt.tls\_level=DISABLED
dbms.connector.bolt.listen\_address=:0.0.0.0:7687
#dbms.connector.bolt.advertised\_address=:7687
HTTP Connector:
dbms.connector.http.enabled=true
dbms.connector.http.listen\_address=0.0.0.0:7474
#dbms.connector.http.advertised\_address=:7474
Can someone please help me solve this issue?

Check /var/log/neo4j/debug.log for any startup errors, it might be that you're missing a dependency.
Did you try to remove the apoc-mongodb dependencies if it works again then?

Removing the apoc-mongodb dependencies solved the problem
