Tunnels with cloudflare

im trying to create a tunnel but when i try to connect the tunnel to Cloudflare with docker i keep getting this error. “there are no free edge addresses left to resolve to”
i am not sure how i can fix this.
im using it on my synology nas drive.


Could you please make sure that this NAS drive are able to access internet / resolve DNS names and if there are no firewall rules preventing from this connection to happen?

Thank you!

Good Morning,
I have checked my firewall and its off its still not letting me turn on the container.

i have attached a photo of my containers available.
