ACC no longer works on Windows 10

ACC no longer works on Windows 10

I have a really weird problem since about two months ago, when ACC suddenly stopped working on my Windows 10 computer. It will scan the network when started up or when I hit the "scan" button, but it no longer finds the NAS.

1. It is not a network or router problem since ACC on my Mac and the AIMaster app on my Android phone both can see the NAS when connected through the same router (an ASUS RT-AC3200).

2. Furthermore, I can still see and browse the NAS in Windows 10 Explorer, and connect and log into it from the Windows computer both by the web interface and by ssh.

3. It is not a Windows Firewall problem since ACC still does not work even if I completely disable Windows Firewall.

4. I am using Malwarebytes Windows Firewall Control as a UI to Windows Firewall, and I can see what happens when I try to use ACC in its log. ACC makes exactly six attempts to broadcast to port 8888 before it gives up. Three of these attempts are from the assigned LAN address of the Windows 10 computer ( and three from the loopback address ( All six attempts to broadcast are marked as BLOCKED in the log.

5. Now, here comes the really weird part. This happens even if I completely disable Windows Firewall and reboot the computer. That is, Windows Firewall Control still logs six BLOCKED attempts to broadcast to port 8888 even though Windows Firewall now is OFF.

My conclusion is that something else (not Windows Firewall) blocks the ACC broadcast calls to port 8888, and that these blocked calls are logged by Windows Firewall Control even though the firewall itself is disabled.

I noted in a thread below that the ASUS "Republic of Gamers III" program is known to block ACC function on Windows computers:


I do not have this program installed, but I do have an ASUS computer (an UX430UNR laptop). Is it possible that some other ASUS program is blocking ACC?

Has anybody else seen this problem? Any ideas or suggestions what I should try next?

Edit: some other tings I tried which did not work: a) Turned on the smb1 protocol. b) Excluded ACC and the entire ASUSTOR program folder in Windows Security. c) Disabled real-time protection in Windows Security. I am not running any other antivirus software.
