Currently testing Growthbook with Vercel's Edge Functions (based on the "A/B Testing with the new Next.js 12 Middleware" example code), but calling

await fetch(FEATURES_ENDPOINT)

gives the following response when deployed to Vercel in Preview:

{ cf: undefined,
  webSocket: null,
  url: '<https://cdn.growthbook.io/api/features/[our> key]',
  redirected: false,
  ok: false,
  headers: {},
  statusText: 'Origin SSL Handshake Error',
  status: 525,
  bodyUsed: false,
  body: { locked: false } }

Works fine locally using

vercel dev

. @future-teacher-7046 did you ever experience this error?

I haven't seen that before. Looks like it's coming from Cloudflare, which I assume Vercel uses under the hood.

Thanks!

Can you try again? I switched the CDN to use a dedicated SSL cert instead of a wildcard one.

Works fine now, thanks for the help!
