Sorry to bother you over the last 2 weeks I have had reports and had myself 520 errors from our server. I know this means our server - But I have checked our logs and I can see no errors.
This happens occasionally, then if we refresh its fine. It also happens on loads to assets in our app.
I checked out HTTP logs but i cant see any failed request, hence I am wondering if the request is getting that far?
The highlighted entry is my retry which loaded, the two calls at :23 and :22 HEAD HTTP 1,1 both say 200
Any ideas, or anything our end that could be causing this?
