We’re hosting several websites with Siteground and can see the below error in all websites’ error logs (just with different .txt file names). Does anyone know what’s causing the error and if there’s something we can do to resolve this, or if it doesn’t need resolving?
I’ve removed info below that I felt looked like a validation key but the validation key that the request is looking for does not match the Global API Key we can generate from our Cloudflare dashboard. What resource is the system requesting that can’t be found?
