Failed to Access Stardog Server

[rong0525]

Description:
Hello,

First of all, I would like to thank you for your excellent work. I have carefully read your paper and am very impressed with the contributions you've made. I am currently trying to run the code from this repository to further understand and learn from your work. However, I have encountered a issue when attempting to connect to the Stardog server.

Troubleshooting Steps Taken:

• Checked DNS configuration and confirmed that Google's public DNS servers are being used.
• Verified network connectivity by pinging 8.8.8.8.
• Attempted to resolve the hostname using nslookup and dig, which both failed to return an IP address for the given hostname.
• Attempted to use curl and wget to connect to the server, both of which failed with DNS resolution errors.
• Confirmed that the domain sd-d63d428a.stardog.cloud does not resolve to an IP address.

Request:
Could you please verify if the Stardog server sd-d63d428a.stardog.cloud is currently available and properly configured? Any guidance on how to resolve this DNS issue would be greatly appreciated.

Thank you for your assistance!
