Unable to mount external encrypted disk

Running Kubuntu 17.10 I have an external hard disk of 500GB split into two partitions of equal sizes. One partition is an NTFS partition and the other is an encrypted partition. When I connect the disk to my laptop, Device Notifier shows entries for both partitions separately.

Output of sudo cryptsetup luksDump /dev/sdd1 is:

When I try mounting the partition with sudo cryptsetup luksOpen /dev/sdd1 lukslvm, it asks for a password. When I enter a correct password, it produces no error.

After this, ls -lA /dev/mapper shows:

Output of sudo lsblk -f is:

Output of cryptsetup status lukslvm is:

/dev/mapper/lukslvm is active.

  mode:    read/write

The device notifier still shows the volume as not mounted.

When I try to mount it using the device notifier, it produces an error informing me that it can not be mounted.

In Dolphin, when I try to mount it, it produces an error:

An error occurred while accessing 'efinso-X53U-back', the system responded: The requested operation has failed:

Error mounting /dev/dm-4 at /media/sandip/efinso-X53U-back: Command-line mount -t "ext4" -o "uhelper=udisks2,nodev,nosuid" "/dev/dm-4" "/media/sandip/efinso-X53U-back"' exited with non-zero exit status 32: 
  mount: /media/sandip/efinso-X53U-back: can't read superblock on /dev/mapper/lukslvm.

I am able to mount NTFS partition without difficulty.

Also, external hard disks with only one encrypted partition on them load without any error.

What could have gone wrong? How do I set it right?

FWIW, there is a chance that last time I used the encrypted partition, I forgot to eject it.

Thanks to user @ukos, in comments the following solution was mentioned and it fixed the issue for me. I'm posting here as possible solution. Pay attention sudo in command, without it, it gives error:

$ cryptsetup luksOpen /dev/sde1 lukslvm
Device /dev/sde1 doesn't exist or access denied.
$ sudo cryptsetup luksOpen /dev/sde1 lukslvm
Enter passphrase for /dev/sde1: 

After I entered correct answer, it opened this disk in file manager too.
