No data in mqtt

[Andre G]

hi,
i am using grafana latest version in docker container and the latest mqtt-plugin.
my mqtt-publisher is mosquitto in another docker container. mqtt is fully functional (other containers are publishing data to mosquitto and others are subscribed t mosquitto successfully).
in grafana i am not able to get data from mqtt, although the test is succesful and i see a connections in mosquitto when connection is tested in grafana.

i tested several topics, from

mbmd/#
mbmd/sunspec1-126/#
mbmd/sunspec1-126/Frequency
mbmd/sunspec1-126/Frequency/#

nothing is giving me any data.

i verified the connection several times, it loogs good:

any ideas?

regards,
andre
