[SOLVED] Incomplete execution of a backup script

[Cromatin]

For a holiday Minecraft event, I have acquired a server through a third party (server at home does not have enough power).
And I wanted to make a backup on my PBS every 4 hours, since it is located in my house network I have to connect via VPN to execute the backup and then disconnect again.

I have written a bash script for this purpose:

#!/bin/sh

# Timestamp
echo ---- START $(date +'%d.%m - %H:%M') ----

# Connect to remote network
wg-quick up cs2-pbs

# Create the Backup
export PBS_PASSWORD=
export PBS_REPOSITORY=
proxmox-backup-client backup root.pxar:/opt/createlive4 --backup-id Create-Something_2 --rate 531250
export PBS_PASSWORD=
export PBS_REPOSITORY=

# Disconnect from the remote network
wg-quick down cs2-pbs

# Timestamp
echo ---- END $(date +'%d.%m - %H:%M') ----

(Password and repo are hidden)

I have also created a cronjob that executes this script every 4 hours.
0 */4 * * * sh /opt/cs2_auto_backup.sh >> /opt/cs2_auto_backup.log

After 4 hours had passed I opened the log, but only saw the beginning and end lines.
Also, no VPN connection was established, let alone a backup.

---- START 30.05 - 16:00 ----
---- END 30.05 - 16:00 ----

When I run the script manually it runs correctly, only the cronjob seems to cause problems.
Would help a lot to finally find the problem, after I have been trying to fix it for days.

Change it to this to also fetch errors in your logs:

0 */4 * * * sh /opt/cs2_auto_backup.sh >> /opt/cs2_auto_backup.log 2>&1

Now everything finally works
