Static Files in wwwroot don't get rendered in Docker container

I'm using a containerized ASP.Net Core (5) Web Api app. The container is (Linux based container) running Debian Stretch. Everything is working fine except that the static files in app/wwwroot of the container don't get rendered when it supposed to be. I even made sure that the imgs, css, fonts files are actually there in the container at "app/wwwroot" and they exist!

also the in Program.cs/CreateHostBuilder(): this line is there

.UseContentRoot(Directory.GetCurrentDirectory())

also, in Startup.cs I did this:

 app.UseStaticFiles();

So, I don't know what could be the problem ? is it related to Rotativa / wkhtmltopdf library, since its generated PDF file should use these static files? or is it related to the Dockerfile itself? this is the Dockerfile:

You might need to set the properties of static files to always copy try this

in visual studio right-click on your file.
Click on the Properties.
Set Copy to output directory to Copy always.

See attached screenshot

the issue wasn't because of path as I thought, it was because the container ip address, thank you everyone
