Not displaying images from node-red-static folder #11

Closed nygma2004 closed 4 years ago

nygma2004 commented 4 years ago

I have a static folder set up in Node-Red settings.js and I place some images there that I want to display on Home Hub: e.g. http://192.168.1.80:1880/gate.jpg. If I open this URL in the browser I get image, so the URL is definitely correct. If I send this URL to Home Hub as a Media, I get a "Error: load failed". Unfortunately there is no more info on this, so I have no way of telling what has gone wrong. Any ideas why Home Hub does not like the Node Red server?

Unsure. You'd have to start looking at various pieces and troubleshooting. Things I'd check:

  1. Does it not like the port? I.e., does it require port 80/443?
  2. Is your static folder not outputting the right headers to satisfy the Chromecast, like content-type, etc.?

Try hosting it somewhere else real quick on your local network and see if you can do it from there to eliminate the node-red static serving as the issue. Normally, I'd setup an nginx proxy around the node-red install for just this reason, so I have a real HTTP server that I can work with.

Thanks for your tip. It looks like Node Red is causing the issue. I have copied the same image to my NAS which also has a web server and that works fine on port 5000. I have Apache web server also running on the PI serving some other bits, so I save my image to /var/www/html and point Google Hub to http://192.168.x.x:8080/gate.jpg and it works just fine. So it must be Node-Red.
