Skywatcher EQ8 connect to pc

Today I picked up a Skywatcher EQ8 mount. It came with the direct to of usb cable (usb connect to mount, bypassing the hand controller)

I started SynScan app, went to settings, selected serial and com 10 Went back to connect and I’m getting the response “Connecting”

then

“Cannot Connect”

Am I doing this right? What am I missing?

Editing because I found the problem: it was a dodgy older app I had downloaded. I found the latest version and it connected with no issues whatsoever.
