Hello @troyjackky

Unfortunately, I was not able to reproduce the problem. Can you, please, check the following?

  1. The address you use for Neo4jDNSUI should include the port number:

  2. When you replace <Neo4j-DNS-Connection> in the src/env file, the port number and the colon should not be included.
  3. You can try rebooting the EC2 instance where Neo4j is running. You should first search EC2 in the AWS console, then select instances, from the instances select the one hosting Neo4j, and finally choose reboot from the instance state dropdown menu.

I hope this helps. If the issue persists, please, provide a screenshot of the error you get in the cell in section 2.2 so that we can investigate further.

Are there any specific setting up or we just follow the instruction from C3_W1_Assignment.ipynb file?

No, following the instructions in the notebook is sufficient. I will report your issue to the team and will inform you as soon as I get any update.
