This is really odd. The error is stating that there is some issue loading the image because something internal within Java is missing. Which version of Java are you using?

 I'm actually having the same issue with my server, seems like something has broke on it. I'm using the latest version of Java btw

Server returned HTTP response code: 403 for URL

The plugin was not able to download the image because the connection was forbidden (code 403). This could be from discord preventing the plugin from downloading the image. I'll see if there is anything I can do on my side, but I think you may need to manually download the image into the image folder for now.
