I have a device, an ESP8266-like, connecting my automower to my wan.

If I hardcode the address to, it is accessible from my phone and my laptop, among others I guess.

If I hardcode the address to, it is not accessible from my phone, but still from my laptop.

I don't get pings back when pinging from the phone, a traceroute end with the phone's own IP, as I do when I traceroute to an unreachable address.

In short, something on the phone seems to be blocking that particular IP. Rebooting the phone doesn't help.

The phone is a OnePlus 5, Android, OxygenOS 9.0.6

EDIT: all devices are on the same WiFi, Ubiquity devices.

  • Is you wan from some router or is that of phone's hotspot? What's the phone's IP address? – Irfan Latif Jun 30 '19 at 15:23
  • All devices on same ubiquity wifi network. – Lenne Jun 30 '19 at 19:56
  • And what's your phone's IP? Anyone here won't be able to know what's going on on your device, unless you provide enough logs and info; how many hosts are on the network, what are their IP addresses, what does ip -n shows, what are the gateway IP and DNS IP, is the router DHCP or you do static configuration completely, can you ping your router from phone etc. Android doesn't have a restrictive firewall, but the routing is really complicated. – Irfan Latif Jun 30 '19 at 21:15
