LUN Plugin. Copying a file from a network disk

[Evg]

Hi!
I have a router with OpenWrt v.23.05.4. A flash drive is connected to it. Ksmbd/Kmod Version 3.5.1/5.15.162.
I'm copying a file from my network storage to my phone. At first the loading is as fast as possible, but then the progress bar freezes for about 30 seconds.

I think at this point the file has already been downloaded. After approximately 30 seconds a message appears.

The file is actually downloaded.

This never happened before, copying was fast.

This sounds like some kind of timeout at the end of the transfer. The plugin seems to wait for some kind of "end of file" packet but never receives it.

Strange, another file manager copies quickly

Then just use that other file manager. It must be using a different SMB library which works better with your server.
