    indeed - though the other argument is that on a non-Cloudflare setup, you won't have any visibility into such errors for visitors who do not report such errors either.

    with Cloudflare you can dig into Cloudflare API to get some stats though for your Cloudflare Zone

    excerpt from my custom Cloudflare API analytics scripts for HTTP status codes
    Code (Text):
    ------------------------------------------------------------------
  Cloudflare Zone Analytics
------------------------------------------------------------------
------------------------------------------------------------------
  Requests HTTP Status Codes:
------------------------------------------------------------------
  "101": 7,
  "200": 47769,
  "204": 1213,
  "206": 7,
  "301": 1020,
  "302": 3949,
  "303": 8297,
  "304": 1321,
  "307": 721,
  "401": 12,
  "403": 430,
  "404": 345,
  "405": 6,
  "415": 1,
  "416": 11,
  "499": 459,
  "500": 13,
  "520": 119

    Also any origin Centmin Mod CSF firewall level or Nginx level blocking will display as Cloudflare error page to visitors as well as Cloudflare won't get a response from Centmin Mod's CSF Firewall too or Nginx.

    i.e. Cloudflare 522 errors Troubleshooting Cloudflare 5XX errors and 523 errors Troubleshooting Cloudflare 5XX errors

    Errors are happening at random and only few times daily.
    And looking at their IP, they are not being limited or block by Nginx/CSF.

    Hmm, I'll just move on and fucos on my user's reported issue.
    They are very sensitive and report any errors or slow response they encounter.

    I see. As part of troubleshooting process do you get them to visit other cloudflare sites to see if it's a problem ? You can setup a 2nd test site on cloudflare on same server or same server/webhost location and get folks to visit that to see if they have same issue or not too. Cloudflare support also can provide logs if asked nicely too.

    Works fine now with 1.17.4 and Dynamic TLS only.

    So issue could be coming from Zero Downtime mod or Hpack.
