I have followed the installation guide and was able to install the graph explorer. But unable to connect to graph DB. Could you please provide the details what i am missing.Thanks.

Can you please provide further details about your configuration? What graph database are you attempting to connect to? Where are you deploying graph explorer? Etc.

I am also having connectivity issue. Deployed graph explorer on EC2 machine and getting synchronization issue with Neptune DB. Neptune is not publically accessible

Now we are able to connect. But data is not getting viewed when we create a RDF manually. Instead if we use SPARQL and insert data it works. What would be the issue?

Check if the port of 8182 is open in Neptune SG for EC2 proxy to access.

Not sure I follow what you mean by "create a RDF manually". Can you please elaborate?

In Neptune, Property Graph and RDF data are stored separately. So if you write data using SPARQL/RDF, you can only access that data using SPARQL in RDF format. Subsequently, if you write data using Gremlin or openCypher (both Property Graph languages) you can only then read that data using Gremlin or openCypher.

Yes it is open when I try to telnet neptune from EC2 machine. Its working fine on 8182 port

@sanchit231 - Are you still experiencing issues? What error messages are you seeing (either from the docker logs or from your browser's Dev Tools console)?
