TL;DR

The issue can likely be resolved by configuring the application to allow requests to private or internal IP addresses, such as http://127.0.0.1:18765/.

Guidance

  • Verify that the error message "Blocked hostname or private/internal/special-use IP address" is indeed related to the IP address http://127.0.0.1:18765/ being blocked.
  • Check the configuration of the OpenClaw web UI and the AI model to see if there are any settings that restrict requests to private or internal IP addresses.
  • Consider adding an exception or whitelist for the IP address http://127.0.0.1:18765/ to allow the image to be transmitted between OpenClaw and the AI model.
  • Review the gateway.err.log to ensure that there are no other errors or issues that may be contributing to the problem.
