Yellow Monitor Icon what does it mean

Midjet76

I have only ever been able to connect to my aunts phone when connected via my tethered wifi.  When I am at home I can't access her phone and hardly ever even see her phone on line.

Now I changed a port setting in her router and now I see this yellow monitor icon in my connections, whereas the rest of the visible pc's or phones are blue, so I can see her phone but can't connect.  Usually on her phone it says no internet connection even though it is connecetd to the internet.

It's driving me crazy any ideas please

Thanks for the PM Esther

I have now managed to add photo

I had problems attaching the said photo using the photo tab

With regards to the away status the remote computer is a phone and two other phones I regularly see remain blue. 

It looks more like it is visible but unreachable/unconnectable for some reason, this has been going on for months and I would dearly love to get to the bottom of it as the phone in question is that of an aging aunt who I am trying to support , remotely LOL

How do I make it go blue?
