Hello Firefox Community,
I'm experiencing a strange issue with my website, https://www.hostgrap.com.
When I visit the site using Firefox, I get the following error:
Bad gateway
Error code 502
Visit cloudflare.com for more information.

Browser: Working
Cloudflare: Working
Host: Error
However, the same website works perfectly fine on other browsers like Chrome, Edge, and Safari.
Troubleshooting steps I’ve tried in Firefox:
Cleared cache and cookies
Disabled all extensions
Cleared DNS and HTTP cache via about:networking
Checked proxy settings (set to system default)
Tried Private Window
Flushed system DNS
Updated Firefox to the latest version
None of the above resolved the issue. The error appears consistently only in Firefox. I’m using Cloudflare for DNS and reverse proxy, and the server is working as expected for all other users/browsers.
Additional Info:
OS: Windows 10 Home Single Language
Firefox Version: 138.0.3
This issue happens even after disabling all add-ons
No custom rules in Cloudflare specifically targeting Firefox or its user agent
Is there something Firefox-specific that could be triggering this behavior with Cloudflare or my server?
Thanks in advance!
