HISTORY: Started with Blynk Cloud - Yea! Created 3 different apps (Lets call them C1, C2, C3)- and had a blast - and they all work. Decided to move to a local server - did a CLONE from the cloud to the local server - all 3 transferred perfectly (Now call L1,L2,L3) YEA again. Built a 4th app (L4) which only exists on the local server. It works fine too.
Wanted to make a CLONE of L2 (app which was cloned from the cloud C2 and is now on my local server). The QR code is created but when scanned fails with “Not a valid Blynk QR Code”. Bummer.
Repeated this with L1 and L3 (again from within the local-server) - these QR codes also fail. Cloned L4 (which was created on local) - and behold it works - (Interesting note: the QR code has about 4x the density as the QR codes from Cloud apps).
STILL MORE TESTING:
Found the old QR codes which were created on the CLOUD server to initially transfer the Apps - And these QR codes scan fine (i.e. I could get C1, C2, or C3) perfectly fine (although they are older versions and not desired).
HELP – I can rebuild stuff from the older cloud version - but concerned that I have something mis-configured on my local server - OR ???
