Unable to access music library on usb drive attached to router

I used to run Moode Audio on my RPI4B.
My music library is located on a disk drive which is connect on a USB port of a TP-Link AX3000 router.
Moode accesses this library using SMB2.0.
YThis worked fine.
I am now trying to run picoreplayer 8.2.0 on the RPI4B and spent quite a while on trying to mount the music library on the routers USB-drive.
Without succes.
I also tried to acess the library via the LMS "Setup Samba Share" section.
But no success either.

In the LMS "Setup Network Disk Mount" sectio i I entered the following specificatios:
Mount Point: /mnt/routerdisc
IP Address: 192.168.0.1
Share Name: myMusic
Share Type: CIFS
Username: guest
Password: anonymous
Options: uid=1001,gid=50

The result is:
[INFO] mount -v -t cifs -o username=guest,password="anonymous",uid=1001,gid=5 0 //192.168.0.1/"myMusic" /mnt/routerdisk
[ERROR] Disk Mount Error, Try to Reboot.

I don't find a way to specify the path to the libary.
What am I doing wrong?
