Hello everyone .
May I ask have you tried checking with the steps from below article?
Therefore, have you checked your access or error log at your origin host/server for any clue?
Is your Nginx working over HTTP or HTTPS?
Nevertheless, over what port does it work?
Maybe you need to re-check over which port is your application / web server working, as it has to be compatible and supported by Cloudflare as follows in the below article:
If it’s working over HTTPS, do you have a valid SSL certificate installed which covers both your main non-www domain and www domain?
Furthermore, what SSL option have you got at SSL/TLS tab at Cloudflare dashboard for your domain? (Flexible, Full, Strict SSL …)
May I also ask, is Cloudflare allowed to connect to your host origin?
Kindly, re-check from below article:
Cloudflare IP address ranges can be found here:
What happens when it’s enabled and the DNS records are cloud (Proxied via Cloudflare)?

I don’t get a 502 error but you should contact your hosting provider to troubleshoot these common causes at your origin web server:
Basically, follow the steps below
- Ensure the origin server responds to requests for the hostname and domain within the visitor’s URL that generated the 502 or 504 error.
- Investigate excessive server loads, crashes, or network failures.
- Identify applications or services that timed out or were blocked.
