Is my DNS configuration correct?

Greetings,

Thank you for asking.

When I try to access your staging.ewagers.com, I got 502 Error returned:

Nevertheless, ewagers.com works fine.

May I ask have you tried checking with the steps from below article?

https://support.cloudflare.com/hc/en-us/articles/115003011431-Troubleshooting-Cloudflare-5XX-errors#502504error

Therefore, have you checked your access or error log at your origin host/server for any clue?

Is your web server for sub-domain listening and working over HTTP or HTTPS? :thinking:
Nevertheless, over what port does it listen/work?

You could determine this by:

  1. Use the “Pause Cloudflare on Site” option from the Overview tab for your domain at dash.cloudflare.com .
  2. The link is in the lower right corner of that page.
  3. Give it five minutes to take effect.

May I ask have you tried using a different Web browser, or tried clearing your Web browser cache?
How about using a Private window (Incognito mode) or a VPN connection if possible?
Is it the same behaviour on your mobile phone (4G LTE, mobile data, cellular)?

Furthermore, when I check the DNSSEC, I see it’s missing the DS record at your domain registrar and I assume you have got DNSSEC option enabled at Cloudflare dashboard?
Can you try to disable DNSSEC at Cloudflare dashboard for your domain name? :thinking:

Kindly, may I suggest looking into below article for more information about why this error happens and how to trobleshoot:
