Random 520 Errors Have Returned (Wordpress Site Hosted on Siteground)

This error started occurring randomly in early August of 2023, and resolved itself after about a week with no explanation or change from my side. “website is returning an unknown error. Error code [520]" . Now, it’s returned again. There are no errors on or problems on the webhost side (siteground). SSL certificate is valid and does not need renewed (even tried installing Cloudflare origin certificarte but no change). I’ve now had to pause cloudflare again because this isn’t making sense, and has to be an issue with cloudflare. Is anyone else experiencing this 520 error issue? I am a paying customer & this is beginning to seem like a waste of money if these 520 errors keep popping back up when there are absolutely no errors on the webhost server.
