Troubleshooting Dust App Error in Hubspot Query Execution

Hi there! I hope you're all doing great 🙂 Quick question: I've replicated Clément FOLLIET - Welcome to the Jungle Dust App to query our Hubspot instance. It seem to be working (sometimes) and I get a response that is satisfactory. However, I often run into this error:

ERROR: Error running Dust app: failed to lookup address information: Name or service not known (code: dust_app_run_error)

Has anyone encountered this error before? If yes, can you please help me?
