I am able to scan a cloned project QR code successfully until the project gets large enough to trigger an error which states “Server is not reachable.” If I then delete a few components, the QR code scans fine.
Note: The QR code for the cloned project gets progressively mode complicated until it become much simpler again - this is the point when the scan fails on the project.
I’ve also reproduced on the main Blynk server by creating a project and adding widgets until it fails to scan a cloned project.
@mattatl For small projects we just put the entire project description within QR code. But when the projects gets too big to fit in single QR code, we instead pack a link to the source server to get a project copy.
In your case, error “Server is not reachable” means application can’t connect to your local server to get project copy.
