[PROBLEM] Radio Stations do not play - Error = Could not resolve host (all stations do this)

[TheOldPresbyope]

Hi, 

Running Moode 8.3.9 on a RPi 3B+ 1GB. 
When I attempt to play a radio station I get an error "Failed to decode <URL>. CURL failed: Could not resolve host <curl>"
No audio plays. 

I'm connected through wifi to my home network, using a static IP address for the RPi.

ETA - I just tried using a static IP address on a moOde 9.1.4 player connected to a WiFi access point. It's working fine. Doing this reminded me that when you choose STATIC address method, five values have to be entered: the static IP address, a network mask (the default 255.255.255.0 works in most home networks), the gateway address (depends on your router), and the primary and secondary DNS addresses. I hope you filled them all with valid entries. Francesco's suggestion to edit the file /etc/resolv.conf is the equivalent of entering the two DNS addresses in the webUI. The addresses he suggests are well-known DNS which are very reliable.

My original post: Why do you need to use a static IP address? As a check, what happens if you reset moOde to use DHCP and reboot? Can you now access the radio stations?

If you really need to use a static IP address (hint, almost nobody does these days), the normal procedure in a home network situation is to set the client (e.g., moOde) to use DHCP and to reserve the IP address for the client's MAC address on the home router. (Details on how to do that depend on the router; you'll have to look it up.)

As an aside, do your ISP and your router offer IPv6 as well as IPv4 services?
