tinyMCE warnings / emoticons not showing up

Hey quick question.

i have a little problem with the htmlarea (tinyMCE) i added the emoticons plugin, it opens but there are no emojis showing.


i get the following warning in my browser console.

Failed to load emojis: Script at URL "http://localhost:8183/tinymce/plugins/emoticons/js/emojis.min.js" failed to load

I had the same issue last year i think with another plugin. But i cant find the solution for it. I already edited my server.xml for mimetype min.js but still no result.

Maybe some of you have that fixed and can help me. Ty

EDIT:
for testing purposes i created the js folder myself in my workspace.metadata... folder and added the following files into it servoy-extra-components/htmlarea/lib/tinymce/plugins/emoticons/js at master · Servoy/servoy-extra-components · GitHub

this works now in developer, but how do i fix this on my productive server? am i missing some settings in my .war export?
