A little help with the Nano 3 please.

All hooked up and connected to my Wifi

Setup my pool etc

Display keeps showing the Please Check Internet symbol, but all is good with my system and the Nano 3 appears on my network, etc.

I cannot get it to mine on any pool.

Mining Status is Fine / Green circle but Network status is 0 ms and red circle, says no active pool or workers.

I can control the miner from the GUI and a IOS app so it is clearly connected.

Any ideas?
