SMB Share STATUS_BAD_NETWORK_NAME

[jolanda7150]

Hi,
I try to access a SMB share through an iPhone app. I get the following error message:
0xc00000cc STATUS_BAD_NETWORK_NAME

- I already verified that the traffic is passing the firewalls(s).
- I've re-applied the ACLs again
- I tried to chmod 755 the shared folder and its parent folder, which results in new @owner, @group @Everyone ACLs.
- I restarted SMB service
- Tried to change the "Traverse" ACL to "Read"
- I tried to add `@everyone read` ACL to the shared folder and its parent folder

My assumption is that this must be a permission issue, but I can't figure it out.
Share configuration and dataset permissions are in the screenshots attached.
The user trying to access the share is called laura.

I have no idea how to find out what's wrong here.

Code:

d---------+  4 root  wheel   4 Sep 17 19:57 /mnt/tank/backups
d---------+  2 root  wheel   2 Sep 17 19:53 /mnt/tank/backups/iphone-laura

Code:

STATUS_BAD_NETWORK_NAME usually means that there's a typo in SMB sharename or servername that your're trying to access.

Possible the iphone app only supports smbv1? Or maybe the hyphen in the name is messing things up.

- The app supports SMB2 and SMB3 too, tried both and automatic mode
- Checked for typo in share name several times
- Tried with both IP and FQDN
- Tried to rename the share to "test" to exclude the hyphens

None of them works.

Why did you mention 'firewalls'? There usually are not any firewalls between the client and server when using smb.

The phone is in an separate subnet.

The phone is in an separate subnet.

Does it still not work if it's on the same subnet? Or do you have other clients on the network you can test with?
