MYCloud EX2 Ultra Wondows cannot access IP address

I have a home network with 5 computers on it, I just got the My Cloud EX2 Ultra and I can access it on 2 of the 5 computers. I have done the internet protocol check, I have check the sharing, I can see it under storage but it coming up with Windows cannot access drive. It is set to a static drive so I am trying to access it through its IP address. I have mapped the drive to no avail and some other things as well. I am at a loss at this point. Yes they are all running windows 10, yes they are all updated to the same software, Yes I have unplugged and restarted everything and then plugged the drive in only to have it only recognized again on the same two computers. I will say that one of the computers is mine and the other is my sons. No i don’t have any tracking programs or anything else. they all have the same settings for virus protection. I can see all of the computers on my network as well.
Please Help!!

Also check to ensure SMB1.0/CIFS is enabled within Windows 10. Microsoft may have disabled it with a recent update.
