HTTPS makeWebRequest - 404, in browser ok or 401

Oh and on device its ok - 200 or 401 without authorization

Hi, thanks for the hint. After reading some of the related links I remembered that I previously had to set 'Use Device HTTPS requirements' in the simulator, clearing this now enables me to download the json file into the simulator.

If you had to uncheck "use Device HTTPS requirement" to work in the sim, you need to use https and not http in your url or there could be something wrong with the certificate on your server.

Does this mean that if it only works in the sim when I uncheck "Use Device HTTPS requirement" then it won't work from real devices? (I have a https certificate from letsencrypt/certbot) Is there a way to debug this? I mean what should I change in my server's ssl config to make it work? 

To help see what's happening, use "View HTTP Traffic" in the sim with the checkbox on and off,

I tried that but when "Use Device HTTPS Requirements" is checked then all I see are the first few non textual lines, that I think belong to the https protocol. I also don't see a hit in nginx on the server, so it must be blocked by CIQ because of the ssl handshake.

Anyone knows how to configure nginx (or any other webserver for that matter) and the ssl for CIQ to be happy?

I have an nginx web server with a Let's Encrypt certificate, and it worked for me. Here's part of my nginx ssl.conf:

ssl_session_cache       shared:SSL:10m;
ssl_session_timeout     10m;
ssl_protocols           TLSv1 TLSv1.1 TLSv1.2 TLSv1.3;
ssl_prefer_server_ciphers       on;
ssl_ciphers             HIGH:!aNULL:!MD5;
ssl_ecdh_curve          secp384r1;
ssl_session_tickets     off;
add_header Strict-Transport-Security "max-age=31536000; includeSubdomains; preload";

I did not change any web setting in VC studio, in fact the only setting I changed is adding -k to the compiler options so it's basically right out of the box. I am simulating a Fenix 7x, but I hope that's not the cause of the different behavior.

Strange, even with fenix7, it's the same, I get 404 with the exact config you sent, when the "Use Device HTTPS Requirements" is checked.

Does the file you are trying to get have any non-json elements in it? Maybe it's some of your headers? I've kept it as simple as I know how:

function noaaRequest(stationID) as Void {
	var url = "https://api.tidesandcurrents.noaa.gov/mdapi/prod/webapi/stations/" + stationID + ".json";
	var params = {"units" => "metric", "expand" => "datums,harcon"};
	var options = {:method => Communications.HTTP_REQUEST_METHOD_GET,
	   :headers => {"Content-Type" => Communications.REQUEST_CONTENT_TYPE_URL_ENCODED},
	   :responseType => Communications.HTTP_RESPONSE_CONTENT_TYPE_JSON};
	var cbMethod = method(:onReceiveNOAA);
	Communications.makeWebRequest(url, params, options, cbMethod);
}

I have the parameters in a dictionary, not in the URL I'm requesting.
