Troubleshooting

Can't access web UI even though Flood starts correctly

If you are running Flood on a host other than your local machine, use --host argument to listen on all interfaces:

--host 0.0.0.0

Flood can't connect to downloader with https protocol even though browser says it has valid certification.

nodejs has a different way to verify tls cert, you will need to include intermediate certs in your tls certs. For example, le provide a fullchain cert and you should use it.
