Hello, my name is Roberto!
I've been making use of this software almost for two years and since a month ago I have noticed that updater can't connect to update apps. Same issue occures on two computers that I have.
I'm runnig PortableApps 16.1.1 on Windows 10 Home 1909.
I have checked configuration on my firewall and Updater has full permission.
Here some pictures
