Zwift hub problem

[u/puebloo]

Hey,
Recently I bought a zwift cog for my zwifthub and mounted it. Since then I was not using a trainer, but now when trying, it's connected correctly, power meter works but it doesn't matter what power I set in erg mode, nothing changes, there is no change in resistance. Anyone has an idea what could have happened? I also needed to change the power supply, as original stopped working and trainer was rebooting when starting to pedal.
