myjdownloader won't pass link to jdownloader container in gluetun network

[truthsword]

I run jdownloader container via the gluetun network, to keep my exit with a VPN IP. Recently I've added the mydownloader extension to Firefox. Within the gluetun docker compose file I have

 ports:
      - 5800:5800 # jdownloader2
      - 3129:3129 # myjdownloader

Within the jdownloader container docker compose I assign the network
network_mode: "container:gluetun"

Both the extension and container show connected to my myjdownloader account.

I've also added the Custom Device IPs and Direct Connection Mode settings.

When I copy a link, the extension window opens and I select to download, and a large checkmark appears, confirming the link is sent. Yet in the jdownloader2 UI, there is no new activity.

Any suggestions here?
