ServerUnavailableError

The Cause

The server connection was refused. The server at the specified origin is not reachable or not running.

This error occurs when:

• The server is not running
• The server is running on a different port
• A firewall is blocking the connection
• The server address/hostname is incorrect

The Solution

To resolve this:

1. Check if the server is running:

# Test if the server responds
curl http://localhost:3000

2. Verify the correct port: Ensure your configuration uses the correct server port

3. Check firewall settings: Make sure the port is not blocked

4. Verify the server address: Confirm the hostname or IP address is correct

If you’re running a local development server, make sure to start it before running Thymian operations that require server access.
