Public Pool not showing hash rate of miners

Hello,

I have a problem with the Public Pool app in Umbrel 1.4.2 running on my Rpi5.

Public Pool is not showing any hash rate but I have 2 Bitaxe mining. Anybody an Idea?

I have already uninstalled the Public Pool app, restarted my node and installed Public Pool app again. Doesn’t change anything. My miners are obviously working but hash rate is not displayed in Public Pool???
