[gdbrehm]

Did you try using just Remote Control alone with MM?

• I have and the error still happening

Description

When I push a remote alert with an image in it with a shell script, the image only appears if the URL points to an image outside my network.

This is the remote script with server names redacted.

#!/bin/bash
curl -X POST http://magicmirror.local:8080/api/module/alert/showalert \
  -H 'content-type: application/json' \
  -d '{ 
    "title": "",
    "message": "",
    "imageUrl": "https://example.local/snap.png",
    "imageHeight": "570",
    "timer": 5000
    }'

Watching the logs on example.local I note that magicamirror.local is not making any at all request ... I have tried http, the IP address, various legitimate and tested hostnames, so it doesn't seem like it's an issue with my URL. I can download and access the image from the MagicMirror's OS with other software.

However, if put in a link from google images or any other random image from the Internet works as expected. I have tried downloading the images that work from the Internet to a local server, that also fails. Naively, I have ruled out hostname resolution and image format. The most basic URL does not make a request according to the logs on local network server, i.e., http://192.168.5.5/snap.png

Expected behavior

Image from a local server will appear as an alert.

Current behavior

Image from a local server does not appear. Image from a server outside my network appears.

Possible solution

None.

Steps to reproduce

Swap a URL from a server on my home network with an Internet URL.

Log

No relevant logs found.

config.js

{
    module: 'MMM-Remote-Control',
    config: {
        customCommand: {}, 
        showModuleApiMenu: true, 
        secureEndpoints: true, 
    }

Additional info

While I continue to suspect it's something to do with my local network, I feel like I have ruled that out with URL variations and wget and firefox directly from the magic mirror's OS.
