@Lichtsignaal I can see where Soft is required when using USB but not for ESP as ESP provides the required gateway. I tested hard and soft this morning as soft is the recommended use with ESP and Uno / Nanos and like @flopes found at Using ESP8266 with BLYNK soft doesn’t work at all. It gives constant login timeouts and I don’t really see the point of soft when using an ESP.
I did notice with hard you can’t use #define BLYNK_DEBUG though.
