Inspect origin web server access and crash logs.

Ensure response header size does not exceed 16 KB.

Disable problematic PHP extensions or Apache modules generating blank outputs.

🚫 What Will NOT Help During an Upstream Outage

If Cloudflare servers are experiencing an active disruption or maintenance window, performing unnecessary destructive changes to your equipment will not resolve connection failures:

Reinstalling or deleting the application: Server authentication and handshake errors reside on platform infrastructure, not your local game files.
Factory-resetting your router or modem: Power-cycling is safe, but resetting router firmware to factory defaults will not bypass cloud gateway errors.
Submitting ISP line complaints: Upstream provider outages affect all internet providers equally and cannot be resolved by consumer ISP technicians.
