I’m experiencing an issue in Firefox where a web-based application loads the main interface, but the interactive content does not appear or remains blank. This happens consistently when the site is accessed through a CDN, while direct access to the origin server works correctly. The issue seems related to delayed or timing-out requests (similar to a 524 timeout), where dynamic content fails to load within expected response times. Static elements render properly, but anything requiring API or server-side processing does not display. This behavior also affects browser-based puzzle apps like [https://spellbee.us/ Spelling Bee], where the gameplay area may freeze or fail to load entirely in Firefox. I’ve tested across multiple networks and devices, and the issue persists only in this routing setup. Has anyone experienced similar rendering or loading issues in Firefox related to CDN timeouts or delayed responses? Any troubleshooting tips or Firefox-specific settings that could help would be appreciated.
