Upload Control not working in IIS

I have a website with the asp.net upload control and it works fine while running it on my computer, but when I upload it to the server it does not work, all that happens is the cursor continues to spin when accessed from chrome and edge on my same computer

I tried it from my mobile and it worked

This is strange, I contacted the web hosting site and it worked from there local computer

Any ideas, if not is there a simple 3rd party one I could use for single and multiple file uploads ?
