TrueNAS SCALE - set Cloudflare Tunnel for Nextcloud?

I have a problem accessing my Nextcloud from domain (ClouDNS)

I have TureNAS SCALE Dragonfish-24.04.1, and Nextcloud 29.0.0 from TrueNAS Catalog.

I installed Cloudflared from this wget

I created the tunnel locally from TrueNAS shell, created the domain from ClouDNS, and already set the NS to Cloudflare and the _acme-challenge to verify Cloudflare. The tunnel status is HEALTHY, I already set the Public Hostname to my subdomain and my Nextcloud local IP.

• I set the credentials and configuration in TrueNAS
• I think there is no problem with the tunnel connection
• I also add my domain to trusted_domains
• But I can’t access the Nextcloud from my domain.

I put my details here.

here testing nslookup and curl -I

My ISP doesn’t allow port forwarding, it’s a Private IP set on my router.

Anyone can help me?
