Yes, as Pescador says, this is Late Blight and removing all the infected material is the way to go now, I am sorry to say. I also have this issue right now in my tunnel and "One is not amused" The spores are able to get through mesh windows or be blown in when the door is open. No getting away from them.
Do collect up all the fallen fruit, as well as every scrap of leaf, and with nothing to live on, any spores around will die. Mostly advice is to burn infected material, and this does at least stop spores from spreading, but sometimes it is not practical to do this. Mine goes in the local green waste, which is sterilised during the composting process
Advice about keeping foliage dry is definitely worth following,although I did this and still have blighted plants and if next year you see curled leve sof brown patches, cut the leaves off to restrict the spread through the plant. This might mean you can get some ripened fruit. Outside I always now only grow blight resistant varieties, which is worth considering nder cover too of course
Sad though, when you see all your plants go like this after tending them so carefully
