4xx and 5xx
No error message
We are having sporadic 4xx and 5xx errors in specific paths of our website. We are unsure if it is related to the f5 load balancer interacting with cloudflare but it does not occur when cloudflare is not on.
Could you please provide the specific paths or domain that encountering the issue? Additionally, please provide the screenshot of the error for better review the issue.
*Paths: The errors happen on multiple paths; for example, we’re seeing issues with paths like:
//WebElements14/wh-externals/assets/fonts/proximanova-regular-webfont.woff
//WebElements14/wh-externals/assets/fonts/proximanova-bold-webfont.woff
//api/oceanapi/client/getaccountinfo
//api/oceanapi/framework/applicationSetting/FV_Default_Landing_Page
Error Types: We’ve seen 404 errors where the origin server returns a 404 response, and 524 timeouts where no origin response is returned.
File Types: The errors seem to be associated with specific file types. We’re investigating this further, but it could be helpful to know if there are any Cloudflare configurations that might affect certain file types.
Session Management: Our F5 load balancer manages sessions via cookies, and we’re wondering if there could be compatibility issues with Cloudflare’s handling of sessions or cookies.
The errors seem to happen randomly, and we’re trying to pinpoint whether the issue could be tied to Cloudflare’s edge, our origin server, or a potential conflict with F5.
