Mac keeps asking to "accept incoming network connections"

I am running Roon Server (latest version) on a Mac mini (Mojave, 10.14.2)
Every time I open the roon app, it asks for this:

I accept and all is well.
But next time I launch the app, the same request again.

All exclusions set in the firewall (Lulu)

Same for Security and Privacy

I tried reinstalling roon server and app - nothing changed.

I have never used lulu, but I feel like this app could be the reason why you are getting those notifications with each launch

Tried uninstalling it, but the notifications are still here.
