Yes, I have cloud access on.
I have use it for 6 months and it’s ok.
I just switched ISP, before my ISP have dynamic public IP but now my ISP doesn’t give any public IP (I behind router so I cannot port forwarding). Not sure how this impact.
My WD still able to email me about restart, so it’s really weird it said no internet access
I’ve tried DHCP it still show no internet access. And it should have because like you mention it can send email and I can ping when ssh to the My Cloud.
I just tried login to mycloud.com and it can display the My Cloud files, strange because the web UI show there’s no internet access on settings - cloud access
