Why not latest 4.0 or 4.1?

There were several changes/fixes in setup network since 4.0.3.

No idea, but I think you can find out more by de-obfuscating the log [1].
If/when you do, please make sure to install debuginfo packages of the exact
same version that you currently have.

But I'd personally not spend time debugging this before upgrading to latest
4.0 at least.

No idea, did you run engine-setup and it finished successfully?

Best,
