Nextj.s / next-auth error

Hi guys,

I have Next.js app deployed on Cloadflare, app has using next-auth for authentication / login … and all is working well on local, but on server I have error i which I always get error from auth pages created by next-auth.

error is: [next-auth][error][CLIENT_FETCH_ERROR]

My question will be are you familiar with this error before and I am assuming that maybe my domain name is not the same as domain name on which app is working on Cloudflare.

So did app working on same domain or is working on some Cloudflare domain ?
Is next-auth supported on Cloudflare.

Cheers
