I'm trying to setup nextauth authentication with NextAuth.js, everything works well with Chrome but with safari, I'm redirected to the error auth page and in the console, I can see:

[next-auth][error][CLIENT_FETCH_ERROR] 
"
https://next-auth.js.org/errors#client_fetch_error"
"Load failed"
{error: {message: "Load failed", stack: undefined, name: "TypeError"}, url: "/api/auth/providers", message: "Load failed"}

I use ngrok, and when I see the request log I see:

GET /api/auth/providers HTTP/1.1

btw I use ngrok, and I've set up NEXTAUTH_URL. This is weird because it works on chrome, like if safari understand 304 as an error or I don't know.
Any help appreciated 🙂
