Assuming that you’re accessing content using Windows SMB Samba.
My Cloud OS5 support SMBv2 and SMBv3 by default. Your other devices may require SMBv1 to be enabled on the My Cloud. The following article may help.

The My Cloud OS 5 had a dedication board located at https://community.wd.com/c/OS5/252
