hard to say since you haven't shown any screenshots of your configuration.

I assumed that the image showing port 8080 open from the outside was sufficient to show that the port is open. I can access my NAS just fine.

So this is bizarre, I pulled up the link and it first said it wasn’t available, but I set my phone down and after about 15-20 seconds it connected. The throughput is terrible, but I did connect. I had not waited this long previously as I was used to connecting immediately.

i use controller so i don't know how it is in stand alone that you use, but all port forwards go lightning fast.. there is no delay at all.
