RuntimeError: Sending request failed

[kabcasa]

Get error message when running following code in Matrix Portal M4
RuntimeError: Sending request failed
and cannot retrieve the json response from this url :
"https://calendar2.priyom.org/events?timeMin=2022-03-04T00:00:00.000Z&timeMax=2022-03-05T00:00:00.000Z"

The execution succeeds with the error:
File "adafruit_requests.py", line 563, in _get_socket
RuntimeError: Sending request failed

I had no problem getting the response with a requests on a python3 script.

Currently my internet connection is a little weak and I suspect that this is the cause.
To confirm I would have liked someone with a better connection to do the test

The HTTP site redirects to HTTPS, and it seems the library doesn't handle redirects with a protocol change.

Not loading the HTTPS site directly could be a certificate issue. Looks like the NINA firmware version on the MatrixPortal is 1.2.2. There have been certificate updates since then. My PyPortal with 1.7.4 loads the HTTPS site. There's an update learn guide here:
https://learn.adafruit.com/upgrading-esp32-firmware

[kabcasa]

@anecdata
Thank you for your comment
why this https url is working
URL = "https://api.openweathermap.org/data/2.5/onecall?exclude=minutely,hourly,alerts"

Anyway i will update the firmware

[anecdata]

There are certificates in the v1.2.2 firmware that handle most HTTPS sites, but there is occasionally one that does not work and it often turns out to be handled by a certificate in the newer bundle in the upgraded firmware.

[kabcasa]

i have updated the frimware but still can't get it

[anecdata]

You're right. I'm not sure what I was seeing yesterday, but I get the same exception on PyPortal with 1.7.4 today.

Also, running ESP32SPI with debug=1, it's apparent that redirections from HTTP to HTTPS are handled properly; Requests gets a new socket with the updated port / protocol.

I think it's still possible it's a certificate issue since this URL also does not work on ESP32-S2, even with the latest NINA submodule update (done to get the updated certificates).

EDIT: turns out I had flashed the wrong version, latest CircuitPython (within the past 6 days) have the new cert included and work without manually supplying the cert.

[anecdata]

It does look like a certificate issue. On ESP32-S2, if I manually supply a certificate (using context.load_verify_locations(cadata=CA_STRING)), the request is successful.

Please could you share how to code this

[anecdata]

That was on an ESP32-S2, that code won't work on MatrixPortal. I did try to supply a custom certificate in ESP32SPI using esp.set_certificate(CA_STRING) (e.g., MatrixPortal, PyPortal), but it's apparently too long:
AssertionError: .PEM must be less than 1300 bytes. Though I may be supplying the wrong format; I used the same certificate string as on ESP32-S2.

This URL does not work without a manually-supplied certificate ...EDIT... on CircuitPython 7.2.0, but it does work on very recent versions with the NINA submodule updated.

[anecdata]

The 1300-character limit (AssertionError: .PEM must be less than 1300 bytes.) apparently arises in the NINA firmware (or perhaps deeper, in the Espressif Arduino code that NINA is built upon):
https://github.com/adafruit/nina-fw/blob/d73fe315cc7f9148a0918490d3b75430c8444bf7/main/CommandHandler.cpp#L34
I've filed an issue there:
adafruit/nina-fw#42

[kabcasa]

@anecdata
Thanks a lot

[kabcasa]

I'm not sure if that can help
https://forums.adafruit.com/viewtopic.php?f=60&t=170089&p=831515&hilit=esp32spi+certificate#p831515

I'm sorry I'm new to certificates . From where did you get the certificate that you use in your code.

[anecdata]

The certificate I used is somewhat random, it just worked in a prior similar case so I tried it here. It's from an Espressif example:
https://github.com/espressif/esp-idf/blob/master/examples/protocols/https_request/main/server_root_cert.pem

Thanks for the forum link. New certs could certainly be built into new NINA firmware. I don't really know much about certificates either, but I thought the esp.set_certificate() function looked like it should do what we needed (like its ESP32-S2 counterpart), but it had the 1300 character limit.

[anecdata]

Looks like that cert has been added to the NINA repo, but it has not yet been re-built and re-released. You can watch the NINA repo for a new version, which (I hope) should fix your issue. Silly mistake above... I thought I had updated my ESP32-S2 to the version (anything since 6 days ago) including the new cert, but flashed the wrong version (I've edited comments above). But now having done so, it works without the manual certificate on ESP32-S2, which is a good sign for when a new NINA version gets released.

[kabcasa]

Thanks again.
But it's working with ESP32-S2 and not for ESP32-SP1 that means we still have the issue even after the NINA will be updated if the limit of 1.3k is not resolved .
We have tested after updated to NINA 1.7.4

[anecdata]

The 1300-byte limit is only for manually-supplied certificates using esp.set_certificate(). Once the NINA firmware is updated with the new certificate permanently embedded in the firmware, this URL should work.

temporarily is it possible to set the requests verify to False as for python
requests.get('https://example.com', verify=False)

[anecdata]

I don't see it in the ESP32SPI API

ESP32-S2 has this:

pool = socketpool.SocketPool(wifi.radio)
context = ssl.create_default_context()
context.check_hostname = False
requests = adafruit_requests.Session(pool, context)

but in this issue (and a prior certificate issue) it was not enough to allow successful loading of the URL.

[anecdata]

@kabcasa If you're in a hurry for this, you can build the NINA firmware. It's a little involved, but it can be done:

Did you already try it in your side 

[anecdata]

It's been a couple of years since I built NINA. I'm not sure how to interpret those errors, this may need someone more expert to weigh in or do the build.

You could file an issue in the NINA repository indicating that a needed certificate has been merged but not built or released. That might make the need more visible.

@anecdata
Hi i could finally update the firmware in Windows.
That could resolve the url request issue.

[kabcasa]

resolved after updated nina-fw firmaware

[crhuber]

Still an issue for me on Circuit Python 8.2.6 and nina-fw 1.7.5 and Pyportal
The cert in question is a cloudflare cert
