Hi I have a problem.
My blynk app disconnects with esp32 or refuses to connect. I supply power to esp32 and other things and when esp32 works on this supply it does not connect. But if I disconnect vin from esp32 and supply power only to it via micro usb cable, it works. Then I connect it to the normal power supply and it’s still connected to micro usb and it works. When I remove micro usb it works for 10 mins and then stops working (disconnects) (led on it still shines).
Here’s code:

int MaxMoist = 0;
