Hello @happyallday! I'm here to help you with any bugs, questions, or contributions related to Dify. Let's work together to resolve this issue!

To address the issue of dialogue not displaying in the browser for Dify version 0.13.0 in a self-hosted Docker environment, you can try the following troubleshooting steps:

1. Docker Configuration: Ensure that your Docker setup is correctly configured. If you are using Docker to deploy Dify and Ollama, you might encounter connection errors because the Ollama service is not accessible from the Docker container. Use host.docker.internal instead of localhost to expose the Ollama service to the network. This configuration should look like this:

   http://host.docker.internal:11434

   This change allows the Docker container to access the Ollama service running on the host machine ^[1].

2. Iframe Configuration: If you are embedding the chat interface using an iframe, ensure that the URL starts with HTTPS, check for any spelling errors, and confirm that the embedded content complies with security policies. Adjust the width and height percentage values in the iframe code if the content is clipped or not fully displayed ^[2].

3. Recent Code Changes: Be aware that recent changes in the Dify codebase related to the chat interface might affect its functionality. The ChatWrapper component has been updated to handle new conversation inputs, stop chat message responding, fetch suggested questions, and support feedback. These changes could impact how the chat interface behaves and displays dialogues ^[3].

If these steps do not resolve the issue, further investigation into the specific environment and configurations might be necessary.
