I am also experiencing these frequent 524 errors and I am also with Siteground. I have spent hours with support but they still point the fingers at Cloudflare! It’s been ongoing for over a month now.
Sorry to hear that. Yeah, it’s the same issue for me. Started about 1-2 months ago and I didn’t change anything. Siteground support couldn’t help and that’s why I submitted a ticket to the CF support now. Did you do the same?
Exact same - literally nothing else I can do!
