What happens if you attempt to access the My Cloud, or map the My Cloud Share using the My Cloud’s IP address? Do you have the same problem?
In the following thread there is some discussion on SMB in Windows 10 when Microsoft borked the SMB2 a while back. May want to take a look and see if anything in there might help. There is a suggestion in that thread to configure the router as the “master browser” for SMB if the router supports such an option.
Thanks for that. Since this issue seems to happen randomly (after a reboot of my PC), the next time it happens I will look at a few things. I’ve never checked to see if my MyCloud shows up under network in Windows Explorer.
Have you updated your Windows 10 PC with ALL of the latest Windows 10 updates?
Are you running a third party Firewall software program? Or have you modified the Windows Firewall to block local network access to the My Cloud? Have you enabled NetBIOS over TCP/IP in Windows 10? Have you enabled local network sharing within Windows 10? Have you installed all of the latest Windows 10 updates?
See the link I posted previously that has this and other Windows 10 suggestions when one has issues accessing the My Cloud under Windows 10.
As a test, try setting the Windows 10 SMB to SMB 1 or SMB3 and see if that works around your issue. See the link I posted earlier in the thread for directions on how to change the Windows 10 SMB version.
Problem is back. I booted my PC this am and all mapped drives were big red X. Clicking on them resulted in the original error message.
Did the Get-SMBConnection command in powershell and Mycloud didn’t show up. SSH’d into mycloud and ran TOP. Didn’t see nmb or smb. Started SAMBA and my mapped drives work. Also ran Get-SMBConnection and mycloud shows up.
I’m not sure this is the same issue, as before, if I started SAMBA, it didn’t fix things.
If you haven’t done so already perhaps you should do a 40 second reset as it sounds like you have something weird going on with Samba on your My Cloud. I would also, as another troubleshooting step, disconnect/turn off all other network devices but the router, the My Cloud, and one single computer and then test again to see if the issues persist. I would reboot just those three devices to perform the testing to isolate if the issue is related to some other device on the local network.
