Re: APCC Pro version update

Ray Gralak

I think we need to concentrate on Windows settings because this is almost certainly not an APCC issue since APCC is able to reach the server via your laptop.

Two more things to look into:

1. Do you have the Wifi LAN configured as private (as opposed to public)? If you choose "public" there will be extra network filtering. Here's how to change this:

2. I wonder if DNS translation is failing. Maybe you can check the IPV4 IP settings and specifically configure one or both DNS servers with your internet provider's DNS server(s).

Also, sometimes it helps to run troubleshooting on the LAN. This probably won't fix the issue, but it couldn't hurt if the other two options above don't help. Whatever this issue is, it is probably something pretty random.

Next step might be to load up an Ethernet network protocol analyzer, like WireShark.

Hi Ray,
I'm running the latest windows 10 and any optional device drivers Microsoft sometimes lists in the update screen.
--- from my machine ---

Edition Windows 10 Pro
Version 20H2
Installed on ‎17/‎07/‎2020
OS build 19042.685
Experience Windows Feature Experience Pack 120.2212.551.0
I'm also running the latest NUC drivers (as checked from the Intel driver support assistant site)
I tried downloading the latest .Net 4.8 framework <
framework/net48> ( but it would not install
claiming I already had the latest.

re ipconfig, windows reports 'Media disconnected' from each of the adapters except for the wifi adapter
I have only ever configured IPV4
I have no IPV6 configured so I suspect it's only listing the address

I then plugged in an ethernet cable directly from the router.
I changed the properties of both wifi and ethernet adapters by removing IPV6
I rebooted with ethernet plugged in so the machine would prefer that over wifi

ipconfig listed no IPV6 but APCC still does not get the latest version

---------- ipconfig results below ---------
