Hey @natz, I don't support this anymore, but it still works, make sure you can ping to google.com from Network -> Diagnostic page.
If you can only ping IP, check your network configuration and wan, you may need to use custom DNS entry if the gateway and LAN are the same IP (which they shouldn't).
I also tried the official package and it broke my web UI, nginx configuration (used for websocket proxy) isn't compatible and uhttpd is replaced for web UI which requires extra steps on older openwrt versions.
