BrokenPipeError in network.fetch

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 806, in socket_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
File "adafruit_portalbase/network.py", line 518, in fetch
File "adafruit_requests.py", line 816, in get
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.

Reproduce the failure with the supplied Matrix Portal M4 sample, comparing the successful fetch_data call with the failing network.fetch URL. Start by reading adafruit_requests.py around _get_socket, connect, and request, then follow the traceback into adafruit_esp32spi_socket.py and adafruit_esp32spi.py. Done means the reported URL no longer produces RuntimeError: Sending request failed, with the existing behavior preserved for the working request.
