Hi guys,
I had my wallet nicely setup until now. Today I try to connect and I see nothing (see picture).
I’m pretty new at this, so it’s probably that I’m not connected to a node or something like that.
Could I get any help please ? That’d be very much appreciated, thanks !
Yes, you’re not connected to a node. Click on the Node button with the red circle and select another node. If you’re unable to connect to any node then there might be something wrong with your connection.
Thanks patmast3r, that fixed it !
Sorry I guess it was a noobish question 
Does this mean the node which I was previously connected to died ? Are nodes like “entry points” to the blockchain ?
Thx 
Hard to tell, could be a number of things.
Those nodes basically are the blockchain Each node holds a full copy of the blockchain and most of them also participate in securing the network by harvesting.
