Android Question SMB Upload fails

[MrKim]

I have two tablets. 1 a 2 year old Nexus. The other a brand new Insignia. Both are running android 6.0.1. Both are connected to the same network. Both connect to my SQL server database OK. Both are running the same code,
I am uploading a file to a windows PC.

        U = smgr.GetString("UserName")
        PW = smgr.GetString("Password")

        SMB1.Initialize(FInfo.RetSub)
        SMB1.SetCredentials(U, PW, "")

        If FInfo.WD.StartsWith("smb:") = False Then FInfo.WD = "smb:" & FInfo.WD
        SMB1.UploadFile(FInfo.LD, FInfo.LF, FInfo.WD, FInfo.WF)

The Nexus works just fine. The Insignia fails with the following error:

Any body have any ideas?

Two differences in the tablets that I can see:
1. I have a user set up on the Nexus but not the Insignia. I can't see where that should make any difference since I am passing the UN and PW.
2. The Insignia is Encrypted - evidently ships that way, can't undo it. The nexus is not encrypted.

Thanks for your help.

Based on the error message it happened when you called DownloadFile.

Sorry, Wrong error message. I corrected above. It fails in both directions.

Sigh, solved it by turning off my firewall. Now I just have to figure out why that works....
