To run Langflow on HTTPS, you can configure the Uvicorn server to use SSL certificates. You can start the server with the --ssl-keyfile and --ssl-certfile options, providing the paths to your SSL key and certificate files. Here's an example command:

uvicorn your_app:app --host 0.0.0.0 --port 8000 --ssl-keyfile=path/to/your/keyfile --ssl-certfile=path/to/your/certfile

Make sure to replace your_app:app with the actual module and application instance you are using. This approach was suggested in a similar open issue ^[1].

@dosu - i have created the certificate but how to use this uvicorn to start langflow. i run it by the following command. python -m langflow run --host 0.0.0.0 --port 7860

To run Langflow with HTTPS using your SSL certificate, you need to modify the way you start the Uvicorn server to include the SSL options. However, Langflow's run_langflow function does not currently support passing SSL options like ssl_keyfile and ssl_certfile directly through the command line or a configuration file ^[1].

To achieve this, you would need to modify the run_langflow function in the Langflow source code to include these options when calling uvicorn.run. Here's a conceptual example of how you might modify the function:

import uvicorn

def run_langflow(host, port, log_level, options, app, ssl_keyfile=None, ssl_certfile=None):
    """
    Run Langflow server on localhost
    """
    try:
        uvicorn.run(
            app,
            host=host,
            port=port,
            log_level=log_level.lower(),
            loop="asyncio",
            ssl_keyfile=ssl_keyfile,
            ssl_certfile=ssl_certfile,
        )
    except KeyboardInterrupt:
        pass
    except Exception as e:
        logger.exception(e)
        sys.exit(1)

You would then call this function with the paths to your SSL key and certificate files. If modifying the source code is not an option, you might need to run Uvicorn directly with the necessary SSL options, as shown in the previous example.

@dosu - where in the source is this file located?

[dosubot[bot]]

The run_langflow function is located in the Langflow source code in the file src/backend/base/langflow/__main__.py ^[1].
