I have Studio One 3.5 Pro on my Windows 10 Pro DAW and Studio One Remote on my Windows 10 Laptop, both 64bit. They are both on the same segment of a wired ethernet LAN, both with the same first three sections of their IP's. However, Remote will not see my DAW when Studio One is open and a Song loaded, or any other time either. I press the Scan button/icon and nothing happens. I have followed all the advice given here that I can find but to no avail. I have disabled firewall/Anti-Virus etc. and still nothing. I have used Port Query and it gives the return code 2 for UDP on the appropriate port (it was the right one just cant recall it as I type this) which I believe means it is an open UDP connection. This is the result both ways DAW to laptop and laptop to DAW. I can transfer files and normal network stuff between the machines other than get Remote to work. I have also tried Wireless to Wireless network in case Remote doesn't work on Wired and still no joy. By the way both machines are behind my ISP router so that makes no difference, and when wireless they are connected to the same Access Point behind the ISP router.
I also have FL Studio 12 and FL Studio Mobile and IL Remote and they all work fine together, though I have moved to Studio One as I love it, though this issue is really annoying as I thought it would be great to have the mixer on the lappy.
Sorry for the extensive question but all the answers seem to relate to iOS Remote accessing Windows or a Mac.
Any help/answers gratefully received.
