(Sorry, not allowed to edit anymore):
I deactivated kubernetes for testing and after a restart, the error went away. But it's still not possible to connect to the engine via WSL2 (e.g. via IntelliJ):
"Cannot connect: org.apache.hc.core5.http.NoHttpResonseException: 127.0.0.1:80 failed to respond"
Is there any migration guide I can follow? Thank you!
