I am using Bower to install several libraries. For demonstration purposes here, I am installing bootstrap. Regardless of the package, I receive the following errors:
It appears as though azsl1326 failed to use bower (git) over port 9418 (git://), then told git to use port 22 (https://) instead. This was still failing, but then opening port 22 got the desired result.
The most direct solution is to open port 9418. This is the port that the git:// protocol uses.
