When running bitbake you will always get a timeout warning.
Steps to reproduce the issue:
1. Run bitbake foobar
No timeouts occur
"WARNING: Timeout while attempting to communicate with bitbake server" is printed out
The issue occurs because in sources/meta-boot2qt/classes/internal-build.bbclass it always tries to connect to yocto-cache.ci.local
Commenting out last lines in that file can be used as a workaround.
