bitcoin core – Bitcoind isn’t starting as system service for some reason

Have bitcoind.service file in /etc/systemd/system with the following contents:

[Unit]
Description=Bitcoin daemon
After=network.target

[Service]
ExecStart=/media/user/2TB/.bitcoin/bitcoind-start.sh

# Process management
####################

Type=forking
PIDFile=/media/user/2TB/.bitcoind/bitcoind.pid
Restart=on-failure

# Directory creation and permissions
####################################

User=user
Group=user


# Hardening measures
####################

PrivateTmp=true

PrivateDevices=true

MemoryDenyWriteExecute=true

[Install]
WantedBy=multi-user.target

and also have a shell script with the following contents and execution rights -rwxr-xr-x 1 user user :

#!/binbash

set -e

sleep 15

echo "Starting bitcoind with script..."

bitcoind --daemon --server -pid=/media/user/2TB/.bitcoin/bitcoind.pid

echo "Start bitcoind with script completed!"

The service won’t start and exists with error:

user@raspberrypi:~ $ systemctl status bitcoind.service

    × bitcoind.service - Bitcoin daemon
         Loaded: loaded (/etc/systemd/system/bitcoind.service; enabled; preset: enabled)
         Active: failed (Result: exit-code) since Mon 2024-04-01 12:57:32 BST; 13s ago

            CPU: 15ms

Any help or ideas why it is happening very appreciated!
