The most common reasons for plugin installation failures in Dify's local Docker setup are network/firewall issues, timeout settings, and Docker internal networking problems.

First, make sure your system and Docker containers have outbound access to port 443, which is required to reach the plugin marketplace and download dependencies from sources like GitHub and PyPI. Firewalls blocking port 443 are a frequent cause of failures (source). Even if you change port mappings in your .env or docker-compose.yaml, containers still need access to port 443 for external downloads.

If you see errors about timeouts or "init environment failed," increase the timeout settings in your Docker Compose files. Set PLUGIN_PYTHON_ENV_INIT_TIMEOUT (default 120 seconds) and PLUGIN_MAX_EXECUTION_TIMEOUT (default 600 seconds) to higher values in both docker-compose.middleware.yaml and docker/docker-compose.yaml (source). This helps if dependency installation is slow or your network is unstable.

Check that your .env and docker-compose.yaml have the correct values for:

• MARKETPLACE_API_URL (should be https://marketplace.dify.ai)
• MARKETPLACE_ENABLED=true
• Plugin daemon ports and API keys are consistent across services
• All required services (API, plugin_daemon, db, redis) are healthy

If you see DNS errors or "failed to lookup address information," your Docker network may be misconfigured or unable to resolve external domains (source). Make sure Docker containers can resolve and reach marketplace.dify.ai and pypi.org.

For more on installing dependencies in Docker, see the official docs: Dify backend sandbox installation.

If you still have issues, please check and share the specific error logs from your plugin_daemon and API containers, your Dify and Docker Compose versions, and confirm your network/firewall setup. This will help pinpoint the root cause.

I've already do the suggestion, but why still failed? the message still the same. the error message is:
Reached maximum retries (3) for URL https://marketplace.dify.ai/api/v1/plugins/download?unique_identifier=hjlarry/mcp-server:0.0.4@e670eb6d28be5d13a892da53446a80631cd48387413607bdb737b782d25cc3f3

what should I do?

This error usually means your Docker containers can't reach marketplace.dify.ai due to DNS or network issues. Here are the most effective steps to resolve it:

1. From inside your plugin_daemon container, run curl or wget to https://marketplace.dify.ai to check connectivity. If it fails, it's a DNS or network problem.
2. Set a custom DNS server (like 8.8.8.8) in Docker Desktop or add dns: 8.8.8.8 under your plugin_daemon service in docker-compose.yaml, then restart all Dify containers. This often fixes DNS resolution issues that cause the retries error [source].
3. Increase the timeout by adding PYTHON_ENV_INIT_TIMEOUT: 320 to the plugin_daemon service in docker-compose.yaml if you haven't already [source].
4. If you use a proxy (like Clash), enable global TUN mode or make sure Docker traffic is routed through your proxy [source].
5. As a workaround, download the .difypkg file for the plugin from the Dify marketplace and install it using the "Install via Local File" option in the Dify web interface [source].
6. If the above doesn't help, try adding FORCE_VERIFYING_SIGNATURE=false to your .env file and restart Dify [source].

If you still have issues, please share the logs from your plugin_daemon and API containers for more targeted help.

I no longer use my company proxy. and I already did whatever you said. but it still cannot install the plugins. why?
