How do I fix this error!

I was able to fix this by getting rid of my proxies that I didn’t know existed. You can find and delete them by clicking on the apple sign in the top left corner → system preferences → network → “advanced…” on the bottom right → proxies and deselect all the proxies within that tab → save and then apply Then I deleted the ankiHub add-on, restarted anki, and the redownloaded the add-on, and it worked!
