HTTP request doesn't work on local network?

[FutureSkillz]

This is a partial code snippet from my APIClient class. I have this method 'run' triggered by a button click.

The code is working for the first 'apiURL' variable for not for the 2nd which is my own locally running API. I know my local API is fine because I can hit it with Postman and my iPhone (same network).
Do you have any clue what might be happening? Thanks!

adamski::RestRequest request;
APIClient() : juce::Thread("APIClient Thread") {}
void run() override
{
	//juce::String apiUrl = "https://jsonplaceholder.typicode.com/todos/1"; //works
	juce::String apiUrl = "https://192.168.1.123:7031/get-single-anonymous"; //doesn't work

	auto response = request.get(apiUrl).execute();
	Logger::outputDebugString("response: " + response.bodyAsString);
}

Does the server on your local network have SSL certificates set up?
Otherwise you probably want to use http instead of https.

Yes it was the https! The moment I used http & port 5074 (the http port for my ASP .NET server) it worked, I was quite surprised haha.
I don't understand though, I'm able to hit that https endpoint in other languages like Javascript (after I setup CORS on server side) no issue.
You still think the solution is set up SSL certificates on server side?

It depends on your use case. If you're developing and running a local server then SSL certificates might not be needed, but if you're sending things over internet, then it's probably very good practice to do so.
