circuitpython: ESP32S2 time.sleep(60) fails but time.sleep(15) works

May be related to https://github.com/adafruit/Adafruit_CircuitPython_Requests/issues/63

On a SAOLA WROVER If I run the code below with time.sleep(15) it executes normally but with time.sleep(60) it executes normally for the first pass throws and error ENOTCONN on the second pass but recovers then fails on the thirds and subsequent passes

Am I doing something wrong? has time.sleep() changed?
