OH3 Speedtest Thing Network binding issues

Thanks. Maybe i did confuse here. I am talking about two different things here.

  1. the speedtest functionallity under Network Binding. This is not working anymore, here is where i tried different server without success.

  2. the Speedtest binding with speedtest cli has not been installed yet. i am struggling to understand how this works as i am running openhab in a Docker.

Question for 1) is, is there someone else experiencing the same problem?

Question for 2) is there a hint how to get this up and running for Docker.

Thank you!
