PWM Fan controller with ESP32

I made a PWM fan hub/controller for my passive cooling gpu. Support DS18B20, NTC, manual as temperature source, Curve-based controller, scheduling,... Temporarily closed-source for development, open-source soon.

For PWM, I'm using an NPN open-collector driver, combined with a tachometer level-shifter/divider which I found from here

Something happened with my account balance...

Credits page showing ~$20 but my harness(configured and using until the problem happened) show Insufficient balance??? The API key is not credit limited, I also tries create new API key and that doesn't fix. Is there any idea what happening? Thanks.
