[Solved] I do not wish to download without VPN

[Schwattmalocher]

Surely the topic has been discussed before, but unfortunately I could not find a suitable thread...

For a better feeling while downloading I got myself a VPN account (Cyberghost).
This works basically fine.
But now I have noticed a very undesirable behavior of JDownloader. From time to time it happens that the VPN connection is interrupted. JDownloader then continues to work without VPN. Is there a possibility to set JDownloader to stop downloads when the VPN is not available?
I am using Ubuntu-Budgie Bionic Beaver and have set up VPN access via the Network Manager (all traffic via VPN).

I am looking forward to answers.
Many thanks and best regards
