GPIOs Not working

My boltIot GPIOs stopped working, but the green and blue led functioning correcting, in status it shows online. I tried connecting all the pins 0-4 and A0, but neither of them is working. Please help me out with this.

Try restarting it and doing it again. Clean the component you’re attaching and check if its dirty or damaged.
