I just tried wd2go.com and did not have any problem with it.
Last week I had my TWC internet service go offline for a short time. I can’t blame Western Digital for that.
During a thunderstorm last week over 3,000 customers in the city where I live lost power. If any of them have and were trying to use their My Cloud device they were out of luck, however they too can’t blame that on Western Digital.
Try connecting to wd2go.com and see what happens.
Edited: It is now 3:25 PM CDST and I was just out getting something cold to drink and tried out my cell phone apps. I was able to use and see photos using the WD Photo app but I was not able to connect using the WD My Cloud app.
