Ksmbd mount error(121): Remote I/O error

[wirtualka85]

Hello

I have a problem mounting a resource from the router to the decoder on Linux. I can access the resource on the router from Windows without any problems. If I issue a share on Windows, I can mount it in the decoder without any problem. The problem is between the decoder and the router.

Router R7800 Software version OpenWrt 23.05-SNAPSHOT, r23780-6f70e09a00 IP 192.168.2.1

Executes the command from the decoder level

mount -t cifs -o username=xx,password=xxx//192.168.2.1/hdd /media/r7800

I have an error

mount error(121): Remote I/O error Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) and kernel log messages (dmesg) mount: mounting //192.168.2.1/hdd on /media/r7800 failed: Remote I/O error

Decder Enigma2

Unfortunately, there is nothing in the dmesg decoder log.

I made dozens of combinations with options vers=3.0 vers=2.1 etc

Does anyone know what could be wrong?
