i have been getting random 520 errors for a few weeks now when accessing my Wordpress page. I have checked my PHP logging data and also from my Apache EC2 AWS server. I cannot find an explanation for this issue. Sometimes it comes, after two or three clicks its gone away. It is completely strange.
I have tried everything you can find on your pages:
Error analyics from cloudflare says the 520 errors come from /admin-ajax.php. But I can not see whats the reason for it.
Can you please help me?
