Issue mounting a network drive using fstab

I'm having a bit of a mare at the moment: I recently rebooted my host server, any my Ubuntu server 20.04 server was unable to mount a network drive again. I had a small issue where the systemd-resolved service wasn't running properly, but I was able to get that sorted. But it still doesn't want to mount the network drive. The mount point definitely exists

ldadmin@LD-DOCKER01:~$ ls /mnt/
plex_data  plex_media  vuetorrent

Here's my fstab file

ldadmin@LD-DOCKER01:~$ cat /etc/fstab
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).

Trying to re-map the network drive

ldadmin@LD-DOCKER01:~$ sudo mount -a
mount error(2): No such file or directory
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) and kernel log messages (dmesg)

Permissions on the local mount point

ldadmin@LD-DOCKER01:~$ ls -l /mnt/
total 12
drwxr-xr-x 2 root root 4096 Nov 12 17:28 plex_data
drwxr-xr-x 2 root root 4096 Oct  1 19:32 plex_media
drwxr-xr-x 2 root root 4096 Oct  1 20:11 vuetorrent

I'm not terribly well versed in Linux, so I'm not sure where I should be looking to get some more specifics. So far I've tried manually mounting the network drive with

ldadmin@LD-DOCKER01:~$ sudo mount -t cifs -o username=*USERNAME*,password=*PASSWORD* //10.11.10.10/media /mnt/plex_data//10.11.10.10/media /mnt/plex_data
mount error(2): No such file or directory
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) and kernel log messages (dmesg)

I've also removed and recreated the mount point, reinstalled cifs-utils, tried mounting to another folder in /mnt/ I am able to ping the server where the network share is located as well. Verified that I can access/mount that share from a different windows machine. Thanks in advance!
