The "Reached maximum retries (3)" error when installing the Tongyi plugin usually means your Dify instance (running in Docker) can't reliably reach the Dify marketplace API. This is often due to network issues, Docker internal DNS problems, firewall/proxy restrictions, or SSL verification failures in your environment. Here are the most effective steps to resolve it:

1. Check network connectivity: From inside your Docker container, make sure you can resolve and reach https://marketplace.dify.ai. Try curl https://marketplace.dify.ai/api/v1/plugins/download?... or ping marketplace.dify.ai from a shell inside the container. If you see DNS errors or timeouts, review your Docker network, DNS, and firewall settings [source].

2. Increase timeouts and adjust environment variables: In your docker-compose.yaml or .env, set:

   PYTHON_ENV_INIT_TIMEOUT=720
   PLUGIN_PYTHON_ENV_INIT_TIMEOUT=720
   PLUGIN_MAX_EXECUTION_TIMEOUT=2400
   PIP_MIRROR_URL=https://mirrors.aliyun.com/pypi/simple
   

   Then restart your containers. This helps if the error is due to slow downloads or dependency installs [source].

3. Disable signature verification: Add FORCE_VERIFYING_SIGNATURE=false to your .env and restart. This can help if SSL or signature checks are failing [source].

4. Manual plugin installation workaround: Download the .difypkg file for the Tongyi plugin from the Dify marketplace using a browser or another machine, then upload it manually via the Dify web interface (Plugins → Install from local file) [source].

5. Clear stuck plugin install tasks: If previous attempts are stuck, clear all plugin installation tasks for your tenant using the admin console or API. This resets the state and allows a clean reinstall [source].

6. Check Docker resources: Ensure your Docker host has enough CPU and memory. Low resources can cause dependency installs to fail or time out [source].

If the problem persists, collect logs from your Dify backend and plugin_daemon containers for more details. Most often, fixing network access or using the manual install workaround resolves this error.
