I'm inside a high performance Ubuntu node and trying to authenticate to my neo4j database. While the same method works flawlessly on Google Colab. I encounter error `Unable to retrieve routing information` I am inside a jupyter notebook which is being forwarded to my local port 8899 from the ubuntu server. ```Python from llama_index.graph_stores.neo4j import Neo4jPGStore username="neo4j" password="3WUQX" url="neo4j+s:/" graph_store = Neo4jPGStore( username=username, password=password, url=url, refresh_schema=False ) ``` ---

@grant_lodge btw I enountered this documentation: [Self-Signed Certificate Generation - Neo4j Ops manager](https://neo4j.com/docs/ops-manager/current/installation/self-signed-certificate/) i tried ssc and default s. Both resulted in error on my server. is there any method available? ---

If you are not in a cluster, can you try the 'bolt' schema instead of 'neo4j'? ---

I have to use the cluster since my local computer will take a long time to process and run the code. (Because I am using for a RAG index) Also I don't know how to use `bolt` schema. do you have any documentation indicating it? (I'm using Neo4j Aura) @glilienfield ---

If using `neo4j+ssc://.` doesn't connect, it is very likely a broader networking issue; if using `neo4j+s://` works in Google Collab but not on your other notebook. Your "high-performance ubuntu" node's networking would be the first place to look. ---

@grant_lodge for both solutions don't work on my ubuntu node. I have a few more nodes. But, I was interested in knowing What can be the likely issue and what possible fixes I can do? I saw Neo4j and a few stackoverflow qnas and they mentioned I could bypass it by having a self-signed certificate. But, I'm not sure how can I download one for neo4j. Also, I have few other nodes which are a bit dormant and accessed only by me. I can use them to fix the networking issues. Can you tell me, what should I run to debug this issue? Because the standard error message is very high-level and does not explain anything. ---

There could be innumerable reasons why your server cannot connect to Aura. If using `neo4j+ssc` didn't work, it is unlikely that the issue is a certificate issue. One thing you could start by doing is pinging the aura instance from your node. You can use ping from Jupyter with ```auto ! ping .databases.neo4j.io ```
