Can't access Fluidd locally via a Browser

[Smyntix]

when I try accessing Fluidd via the web interface (after having completed the whole setup and with klipperscreen working), I get a "browser can't connect to the server" error.

when I try accessing the network tab on klipperscreen I get this error:

failed to initialise
this panel needs Networkmanagerinstalled into the system
and the appropriate permissions, without the it will not function

Failed to detect NetworkManager Service

I solved by reinstalling Fluidd and changing the default port to 70
