Unifi-network-application wifiman speedtests not working

Recently migrated/installed unifi-network-application and it seems to be working for managing my unifi network, however the Unifi Wifiman App can’t seem to find or offer speed testing.

Does anyone have any troubleshooting information about this? Should the Wifiman app allow me to do speedtests from wifi clients to the controller docker container, as it does for the Dream Router natively?

All I could find is this and nobody has revealed the solution. The ports are all open and available (using the recommended docker compose with port 6789 https://community.ui.com/questions/WiFiman-with-Unifi-Network-running-in-Docker/5a0ad294-e6fc-4ca6-96fe-e68263914334
