Trying to remote mount SMB folder

Surely, what you are looking for is Control Panel > Remote Folder

I obviously know where the Remote Folder option is, but I'm having issues mounting an SMB folder and getting a "Resource path unavailable" error despite providing all the required details - I think this was pretty clear from my initial post.

Sorry that we misunderstood your description.
If it is an SMB connection under the same LAN, you do not need these.
Please take a screenshot of the mounting settings page of the Asus router. We need to know if you have any setup errors.

Here you go. My LAN IP for the ASUS router is 192.168.50.1. I've also attached a screenshot of the error message I get from TOS (Remote source path unavailable). Again, this is strange because I have zero issues connecting to this share with any other device in my network. The redacted username is the same one I'm using in the TOS Remote Mount Folder function.

Is the 'Destination Path' empty?

No, it is not empty. You would know the Apply action is disabled until you select a Destination folder, so you can't even trigger the "Remote source path unavailable" error if the Destination field is left blank. I had purposely timed the screenshot to capture the error message even if it obscures the Destination field as the error message has more troubleshooting value.

No, I meant is the destination folder itself physically empty of files/folders (as stated in the help file).

Yes, the destination folder is also empty.

Thank you for your feedback. Our laboratory will follow up on this issue.

I've isolated the problem as a potential SMB incompatibility between my ASUS AX88U router and the F4-423, as I was able to remote mount another SMB share from another device on the network within the NAS.

Am I able to extract logs about how the SMB connection fails? The "remote source path unavailable" error message is not very helpful and is not even mentioned in TerraMaster documentation.

The issue persists on both the stock ASUS and Asuswrt-Merlin firmwares. Thank you.
