The error log you’ve shared indicates an issue with a UiPath Document Understanding process, where a machine learning model extraction attempt results in a server error (HTTP 500). This error typically means there’s a problem on the server side, making it unable to process the request properly. The specific message within the error, “Name or service not known (du-metering.uipath.com:443)” , suggests a DNS resolution issue or a connectivity problem to the specified service endpoint.
1-- Verify if there are any network security configurations (like firewalls or DNS filters) that might block access to du-metering.uipath.com
2-- DNS Resolution

  • Test if du-metering.uipath.com can be resolved from the machine. You can do this using command line tools like ping or nslookup.
    3----If the DNS resolution fails, you might need to check your DNS settings or switch to a more reliable DNS server (like Google DNS or Cloudflare DNS).
    4— . Check UiPath Services Status
    5—Visit the UiPath status page to check if there are any ongoing issues with their services,
    particularly those related to Document Understanding or machine learning model hosting.
    6—Ensure your UiPath robot and Orchestrator are configured correctly to access external services. This includes checking any relevant proxy settings.
    7— Update UiPath Packages
