i can't upload to my arduino (uno)

download all the data but when it tells me to reload the page i do but it says is says "something went wrong"

Not much to go on here so I will try my best.

I have never seen the “reload page” so maybe tell us a few things to see if it can be narrowed down.

OS ?
Browser and version ?

Turn on Console in preferences Try to upload a simple example such as blink and copy and paste that output from the console over here please using code tags ( </> )
