OH3 LG webos pairing/secret key

Hi,

I can’t seem to retrieve the secret key or prompt screen for pairing my OH3 instance with my lg webos TV. I got it working on my previous OH2 setup, but i only get this error, now on OH3:

I’m running OH3 in docker on a Linux Ubuntu 18.04 server.
Anyone know what this log message means?

anyone? would love to ask for some advise
