no icon while Running locally

[frsauvage]

I am trying to use phosphorwebui locally with a remote server.
I figure out nearly everything - : CORS, x-auth-token, origin: *, CSP - everything except ... icons !

I guess it is a stupid configuration somewhere, any help would be appreciate,
I apologize for my ignorance,

I can reach http://mylocalhost:8080/app/assets/icons ... but it is like if icons are excluded ?

I can even inspect the webpack path : nothing wierd as PublicPath is / and /app/assets/icons are present :

I don't know what I miss ?

Best Regards,
Francine
