Network storage will not mount. Config error?

Configuration
1

I have a hard drive connected to my network that I want to use for backups. It is connected via my ASUS router using their samba share feature.

Windows PC works fine to access this folder, but I cannot get HA to accept the share.

The error and configuration are below. On my Windows PC, I can access the share via path \\ROUTER-DRIVE\Files\HA Backups\.

Any idea what I could be doing wrong?

I had a network share on a Mac mini that I was using for backups but right around the time the new backup updates dropped it stopped working and I could never connect again even when using known to be accurate user/pass. I’m only commenting to see if someone weighs in with something that might help.

What are the protocol settings for this?

4

Try using the exact IP address of the router instead of using the network name. (Guessing the router won’t be changing IPs lol)

On our Asus routers, the gateway IP you’d use is 192.168.50.1

Here is the configuration. It’s pretty simple and my Windows PC can see the drive. I do not have any media servers or UPnP configured.

I thought the same thing and tried it yesterday. No dice.

My guess is that it is using SMB 1.0/CIFS. A quick google search seems to confirm it.

Try changing this:

I tried both v1.0 and v2.0 and they both return the same error as before. Could there be some other conflict I’m not considering?

Check the logs on your router and the host like the error says.

^ This, check logs in the Asus UI first

If that doesn’t return any info, try setting Remote Share to ROUTER-DRIVE also

The ASUS routers shows nothing new in the general log (or any log) after I try to mount the remote drive in HA.

FYI, theh HA Host log shows this, which isn’t very helpful:

2026-01-10 10:15:59.056 homeassistant systemd[1]: Mounting Supervisor cifs mount: NetworkBackup...
2026-01-10 10:16:02.678 homeassistant mount[394858]: mount error: could not resolve address for ROUTER-DRIVE: Unknown error

2026-01-10 10:16:02.684 homeassistant systemd[1]: Failed to mount Supervisor cifs mount: NetworkBackup.

I’m wondering if I have some other feature that’s turned off that shouldn’t be for this to work. However, if my PC can get to this drive, it seems that HA should too. I wonder if this is an ASUS thing.

Still no luck. I tried a few permutations too (including the IP address), but still error’s out and ASUS shows nothing in the log.

You need to specify the ip address of your router in the server field. Home Assistant cant resolve “ROUTER-DRIVE”

I’ve tried using the IP address of my router (192.168.50.1). It gives the same error unfortunately. I also tried the earler samba versions without success.

15

Show your config and the error log when using the ip address.

I got it to work, but it requires a strange sequence done exactly like below. I suspect a weird samba implementation on my router. Here is the sequence that worked:

  1. First, reset a samba user (delete user and add back the same user). Why this is required is unknown.
  2. Use the following settings exactly:
    • Server must be IP address
    • Use Samba version legacy (2.0). DO NOT USE v1.0 or v2.1.

Thank you @tom_l for helping out. I would have given without your ideas to test.
