Example error InvalidHostAddress

[MonsieurRz]

So far so good I successfully build libkrunfw and libkrun (Asahi fedora remix 38).

It is certainly a host configuration problem on my side but I cannot put my finger on it.
But when I try the example I run into this error:

thread '' panicked at 'called 'Result::unwrap()' on an 'Err' value: InvalidHostAddress', src/libkrun/src/lib.rs:228:50
