Question
524 timeout, from nodejs application

Asked by acranch
Hi, I have a nodejs application running on digital ocean where users are uploading files to an external site.
Lately these files are getting 524 timeout errors more frequently than not - and i cant see any reason why. If I am running the application locally on my machine this issue does not happen. It does not appear to matter if the file size is large or small.
Apologies if this is not enough context.
Here are the headers:

Hi there,
It seems like this response is coming from Cloudflare. Have you tried temporarily disabling Cloudflare and see if this problem occurs?
How long does it usually take to complete the upload request?
Best,
Bobby
