Seems your DNS doesn’t work.

this also mean either DNS issues or network issues.  
Please check your public IP here: [Open Port Check Tool - Test Port Forwarding on Your Router](https://www.yougetsignal.com/tools/open-ports/) and compare it with WAN IP, they should match otherwise port forwarding will not work.
