So, you are at home, trying to connect your personal computers to your MyCloud, which is connected to the router providing your personal local network at home?
You are not trying to connect to your MyCloud from anywhere outside your home?
I’m not sure why your employer’s cloud service would have any relevance for your local network. If my employer tried to get me to use my own computers for work purposes, a) I’d be very surprised (violating security policy) and b) would politely decline…
How exactly are you trying to connect to the MyCloud? Using File Explorer, and mapped network drives, or some other method?
Can you access the Dashboard?
