Shared Folders from External HDD Folders Not Accessible in Android

All of my shared folders from internal HDD are accessible from my android phone via es file explorer (latest version).
But all of my shared folders from external HDD Folders visible but NOT accessible!

I'm really out of ideas.
I have already tried removing workgroup. Also checked the shared properties of the folder in the external HDD and "everyone" is there. "Everyone" is also present in the Security.

Please help!

most windows networking REQUIRES a password for security, set one for the share on the HDD AND use it ! normally you only need to do this once when connecting for the 1st time....

You may have to change the Permissions on the Share too , it seems Win10 now sets them up as Read Only , so yu need to click on the Permissions tab and check Full Control.

not sure what you mean by "removed workgroup" ? you can name it anything you want ( ie Mike75) but you NEED the Workgroup so all computers on the network can see each other...they must ALL be in the same workgroup.
