Openhab can't connect to Synology Surveillance Station

  • Platform information:
    • Hardware: Sysnology RT1221
    • OS: Docker
    • Java Runtime Environment: 11
    • openHAB version: 3.4.1
  • Issue of the topic: I am trying to install the Synology Surveillance Center Binding on Openhab3. When I try to create a Thing in the UI it always fails. Logs show a socket timeout error. I am using http on port 5000, which is the same port the UI uses. Does anyone have any suggestion for troubleshooting or fixing this?
