For anyone else who reads this, I have an EX4 and the problem is the same. I separate devices using sub netting. I am not changing my network arrangements because I separate all the device for security purposes as I don’t want generic IoT devices being able to access/hack PC’s on the network. OS3 worked perfectly but OS5 broke this arrangement. If you use sub netting, DONOT upgrade. I have logged a formal support request with Western Digital and am awaiting a response to the issue
Firmware 5.04.113 and 5.05.111 restricted access to the dashboard to local network and same subnet.
Firmware 5.06.115 allows access to the dashboard from different subnets but not over the internet.
If you cannot access the dashboard in 5.06.115, chances are you have more than different subnets between your computer and the My Cloud OS 5 device as the adminUI will block and deny any and all access if the source is coming from a Public IP address.
If would be interesting to know more about your network configurations.
It seems the dashboard access only works for ip ranges 192.168.x.x and 172.16.x.x. Many hours wasted figuring this out and changing settings across my network.
Well,
I would not define that as a solution actually. You can do that for simple network setups, but when you have lots of devices connected with static ip rules it becomes extremely time and costs consuming to reset the whole world for just an issue on a single device. Maybe you can do that in home arrangments, but for small\medium offices it is definetly worth changing the nas for another one of different supplier and, for sure, not considering WD products in future hardware refills\upgrades.
I really can’t understand the reason for this, let’s call it, “upgrade” .
@SBrown Hi S Brown, configured ip range. Changed to same subnet. You’re right, it was different subnet over internet. By changing its subnet range, its working now. Issue has been resolved. Thank you for providing information in this regard.
@chenxiong the access policy only affects the AdminUI, dashboard and not FTP Server.
Check your FTP Client Software to see if it is using SSLv1.0 which is not supported in OS 5.
