Sending POST to HTTPS results on "Could not create a secure connection"

[Hiranus]

As is stated in topic.
I want to create microservice on docker that I can send requests to. I can send requests via web browser just fine but when I try to do it with computercraft I get error

(dont worry about WeatherForecast, that part is from template)
Request to the same address done via Swagger

Here is my HTTP config. What should I do to fix this?

#Controls the HTTP API
[http]
	#Enable the "http" API on Computers. Disabling this also disables the "pastebin" and
	#"wget" programs, that many users rely on. It's recommended to leave this on and use
	#the "rules" config option to impose more fine-grained control.
	enabled = true
	#Enable use of http websockets. This requires the "http_enable" option to also be true.
	websocket_enabled = true
	#The number of http requests a computer can make at one time. Additional requests
	#will be queued, and sent when the running requests have finished. Set to 0 for
	#unlimited.
	#Range: > 0
	max_requests = 16
	#The number of websockets a computer can have open at one time.
	#Range: > 1
	max_websockets = 4

	#Limits bandwidth used by computers.
	[http.bandwidth]

	#Tunnels HTTP and websocket requests through a proxy server. Only affects HTTP
	#rules with "use_proxy" set to true (off by default).
	#If authentication is required for the proxy, create a "computercraft-proxy.pw"
	#file in the same directory as "computercraft-server.toml", containing the
	#username and password separated by a colon, e.g. "myuser:mypassword". For
	#SOCKS4 proxies only the username is required.

	#
	# - "action" (optional): Whether to allow or deny this request.
	# - "max_download" (optional): The maximum size (in bytes) that a computer can download in this
	#   request.
	# - "max_upload" (optional): The maximum size (in bytes) that a computer can upload in a this request.

Is that microservice running with TLS/SSL? Have you tried using http as the protocol in the url instead of https? Is the certificate self-signed? What Minecraft version are you using?

[SquidDev]

This is more specific to whatever code is running on your server, so afraid that's harder to answer without knowing more about the code there.

I suspect you'll need to pass the content-type header (and possibly accept) too.

[Hiranus]

I tried passing same header as is in swagger but I got nowhere

Even if I simplify endpoint to just accept string it still doesn't work.

as for what is running on docker - it's your ASP.NET Core Web API project, And it's super bare-bones as it's just Visual Studio template with one additional post endpoint

        [HttpPost]
        public void ItemsAsync([FromBody] Item items)
        {
        }

tostring(item) -- Do you have an __tostring metamethod for converting your item object to a string? By default, doing tostring on any table-type object will just return "table: ptr". I've not looked at the host code, but its possible it's expecting valid json data, and table: xxxxxx is invalid.

[Hiranus]

After some fiddling around with the code I got it to work. But I could swear that I tried it earlier and it didn't work... anyway, thanks for your help guys. SSL for HTTPS certificate was also a thing, so I will have to solve that at a later date, but for now I'll go with HTTP.

local header = {Accept = "*/*", ["Content-Type"] = "application/json"}
local rs = peripheral.wrap("bottom")
local rsItems = rs.listItems()
body = textutils.serializeJSON(rsItems[1])
http.post("http://localhost:32775/WeatherForecast",body,header).close()
