It seems you have tried all options. This issue needs assistance from Motorola folks. Lets wait to hear from them.
The good news is that we are aware of the issue and we are in the process of implementing an alternative for our git servers using Github. This would allow our build servers to clone a user’s github repo, and then build their source (thus by-passing our git servers). We are in the middle of developing this for our ‘test’ instance. We hope to have this up soon (at least in test), but I can not give an ETA.
The bad news is that you basically just have to keep trying.
