What is wrong with deluge webui?

[imaskingadvice]

Ok I only do basic things in deluge (so please bear with me if I sound dumb). I have sonarr set up and sonarr uses the deluge webui to download torrents. It was working fine but now sonarr says "download pending, download client unavailable". I went to check the webui and it says this is when go the the address

I have no idea why. Deluge on my computer works fine. I'm running windows 10 with deluge 1.3.15. I set up sonarr for my parents recently and we both and the same indexer (with the same API Key), but I don't think that would do anything.

Ok I was able to fix it by restarting daemons. Is there anyway I can stop this from happening in the future?
