Summary
api/iframe-check: When upstream returns HTTP 403 and Cloudflare signals (cf-mitigatedorserver: cloudflare), respond withtype: cloudflare_challengeand clearermessage/detailsso DevTools and the IE error UI explain server-side fetch limits.useInternetExplorerStore: Document why bareryo.luis not inDIRECT_PASSTHROUGH_DOMAINS(X-Frame-Options) and that proxy fetch can still fail on CF.Root cause (manual investigation)
https://ryo.luis loaded in “current” mode via/api/iframe-check(not direct iframe) because it cannot be embedded cross-origin fromos.ryo.luwhen the site sendsX-Frame-Options: SAMEORIGIN.curl -sSIL https://ryo.lufrom CI-like environments returns 403 withcf-mitigated: challenge, so the proxy cannot retrieve HTML for embedding.Testing
