BrokenPipeError in network.fetch

[dyeazel]

I'm getting an error with network.fetch on an Adafruit Matrix Portal M4.

Error details:

Traceback (most recent call last):
  File "adafruit_requests.py", line 527, in _get_socket
  File "adafruit_requests.py", line 757, in connect
  File "adafruit_esp32spi/adafruit_esp32spi_socket.py", line 75, in connect

  File "adafruit_esp32spi/adafruit_esp32spi.py", line 284, in _check_data
BrokenPipeError: Expected 01 but got 00

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "code.py", line 29, in <module>
  File "adafruit_portalbase/network.py", line 518, in fetch

  File "adafruit_requests.py", line 661, in request
  File "adafruit_requests.py", line 508, in _get_socket
RuntimeError: Sending request failed

sample code:

import board
import terminalio
from adafruit_matrixportal.network import Network

# Get wifi details and more from a secrets.py file
try:
    from secrets import secrets
except ImportError:
    print("WiFi secrets are kept in secrets.py, please add them there!")
    raise

network = Network(status_neopixel=board.NEOPIXEL, debug=False)

if not network.is_connected:
    # connect to the network defined in secrets.py
    print("connecting")
    network.connect()

    # connect to a test page to show the network is working
    print("fetch test")
    response = network.fetch_data("https://api.sunrise-sunset.org/json?lat=36.7201600&lng=-4.4203400")
    print("")
    print("-" * 40)
    print(response)
    print("-" * 40)

# connect to another page that fails
print("fetch zones")
response = network.fetch("https://www.yeazel2.net/")
print()
print("-" * 40)
print(response)
print("-" * 40)

if you try the URL ( https://www.yeazel2.net/ ) in a browser you'll see that it works.

I have the same issue with very similar code but a different API url: https://opensky-network.org/api/states/all?lamin=-2.0609&lomin=51.4238&lamax=-1.9510&lomax=51.4580

Both are using Let's Encrypt, and me too. I' am checking how to add this CA validate or ignore SSL verification. Keep in touch!

You may need to update the NINA firmware on the ESP32 for an updated certificate bundle:

Thanks @anecdata !!! First Upload Passthrough Code and after Download NINA Firmware. It´s important the first step.

Yes, updated NINA-FW has new root certificates: adafruit/nina-fw#57. Note that there is still a problem with at least some elliptical cryptography cert chains: adafruit/nina-fw#58
