Hi, I'm trying to retrieve METAR (weather) info from my local airport using a MKR1000 and WiFi101 library. My problem is that I make a request in HTTP while it looks like the server expects a request in HTTPS. Below is the answer I get : Starting connection to server... connected to server HTTP/1.1 302 Object Moved Location: https://tgftp.nws.noaa.gov/data/observations/metar/stations/XXXX.TXT Content-Type: text/html Cache-Control: private Connection: close This object may be found here disconnecting from server. Am I using the right library ? Is my MKR1000 able to make a HTTPS connection or shall I upgrade to MKR1010 ? If yes, Is this why MKR1010 embeds an encryption chip ?

Your code works fine on my WiFi 1010. I just changed #include to #include . I do not have a WiFi1000. If you are on a work or school network, try from your home network or vice versa. Attempting to connect to SSID: MYSSID Connected to wifi SSID: MYSSID IP Address: 192.168.XX.YY signal strength (RSSI):-60 dBm Starting connection to server... connected to server HTTP/1.1 200 OK Date: Mon, 12 Aug 2019 18:11:24 GMT Server: Apache X-Frame-Options: SAMEORIGIN X-Content-Type-Options: nosniff X-XSS-Protection: 1; mode=block Last-Modified: Tue, 21 May 2013 11:31:29 GMT ETag: "xxxxxxx-xx-xxxxxxxxxxxxx" Accept-Ranges: bytes Content-Length: 76 Vary: Accept-Encoding Connection: close Content-Type: text/plain; charset=UTF-8 Strict-Transport-Security: max-age=31536000; includeSubdomains; preload 2013/05/21 11:30 XXXX 211130Z 07004KT 360V140 9999 FEW030 17/09 Q1021 NOSIG disconnecting from server.

Here's what I get when I run it on my MKR 1000: Attempting to connect to SSID: mckinley_guest Connected to wifi SSID: mckinley_guest IP Address: 192.168.0.103 signal strength (RSSI):-67 dBm Starting connection to server... disconnecting from server. I have the latest WiFi firmware installed on my MKR 1000.

Since the connection fails (the line "connected to server" never appears), there will never be an HTTP response. Could be a problem with the certificate validation but that happens inside the WINC1500. Perhaps the WiFi101 library maintainer would have some insight.

I just had a try at adding the SSL root certificate for tgftp.nws.noaa.gov to the MKR 1000 using Tools > WiFi101 / WiFiNINA Firmware Updater. The certificate process seemed to go fine but then I ran the sketch again and got the same result as before.

The possibility exists that the failure is a bug in the WINC1500 firmware. The WINC1500 firmware is closed source so there is no way to see what it does. Perhaps the WiFi101 library maintainers know more about debugging TLS connection failures.

there is some SSL related fix in the GitHub repo [image] Commits · arduino-libraries/WiFi101 Wifi library for the Arduino WiFi 101 Shield. Contribute to arduino-libraries/WiFi101 development by creating an account on GitHub.

Hi gbafamily, pert, Thank you for trying my code. This is surprising it works on MKR1010 and not on MKR1000. I'm currently connecting from home network. I can't do it at work so I tried on my cell phone, with the same result. I got a redirection response in HTTP, but no response in HTTPS. I then took a Yun shield lying in a drawer, and put it on a ZERO, updated it's firmware to 1.6.2. I used the HTTPClient example of the Bridge library, that I modified. Unfortunately I got still the same result, a redirection answer for an HTTP request and no answer for an HTTPS one. BTW, I'm using library WiFi101 version 0.16.0 and MKR1000 is running 19.6.1 firmware.

there is a fix. did you try it?

@Juraj, I'm guessing the fix you're referring to is this one?: Removed DHE SSL ciphers to fix issue https://github.com/arduino-libraries/WiFi101/issues/270 committed 01:02PM - 02 Jul 19 UTC [Rocketct] Rocketct +1 -1 I just tried again with the MKR 1000 and the beta version of the WiFi101 library (which contains that fix) and I still get the same result as before. I tried it with my MKR WiFi 1010 and I get the similar results (working I assume) as what gbafamily posted.

As noted the 1000 and 1010 are two different approaches and require two different libs eg the wifinina and wifi101. Strongly suspect therein lies the issue. They are after all two different boards despite the same MPU. Bob.
