cannot run eb push to send new version to elastic beanstalk

I have just set up a new project, the elastic beanstalk environment is running ok with sample application. this was all set up with eb cli.

when I try to do eb push with my new application i get the following

Traceback (most recent call last): File ".git/AWSDevTools/aws.elasticbeanstalk.push", line 57, in dev_tools.push_changes(opts.get("env"), opts.get("commit")) File "/Users/Mark/workspace/edu/gc/.git/AWSDevTools/aws/dev_tools.py", line 196, in push_changes self.create_application_version(env, commit, version_label) File "/Users/Mark/workspace/edu/gc/.git/AWSDevTools/aws/dev_tools.py", line 184, in create_application_version self.upload_file(bucket_name, archived_file) File "/Users/Mark/workspace/edu/gc/.git/AWSDevTools/aws/dev_tools.py", line 145, in upload_file key.set_contents_from_filename(archived_file) File "/Library/Python/2.7/site-packages/http://boto-2.28.0-py2.7.egg/boto/s3/key.py", line 1315, in set_contents_from_filename encrypt_key=encrypt_key) File "/Library/Python/2.7/site-packages/http://boto-2.28.0-py2.7.egg/boto/s3/key.py", line 1246, in set_contents_from_file chunked_transfer=chunked_transfer, size=size) File "/Library/Python/2.7/site-packages/http://boto-2.28.0-py2.7.egg/boto/s3/key.py", line 725, in send_file chunked_transfer=chunked_transfer, size=size) File "/Library/Python/2.7/site-packages/http://boto-2.28.0-py2.7.egg/boto/s3/key.py", line 914, in _send_file_internal query_args=query_args File "/Library/Python/2.7/site-packages/http://boto-2.28.0-py2.7.egg/boto/s3/connection.py", line 633, in make_request retry_handler=retry_handler File "/Library/Python/2.7/site-packages/http://boto-2.28.0-py2.7.egg/boto/connection.py", line 1046, in make_request retry_handler=retry_handler) File "/Library/Python/2.7/site-packages/http://boto-2.28.0-py2.7.egg/boto/connection.py", line 919, in _mexe request.body, request.headers) File "/Library/Python/2.7/site-packages/http://boto-2.28.0-py2.7.egg/boto/s3/key.py", line 815, in sender http_conn.send(chunk) File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/httplib.py", line 805, in send self.sock.sendall(data) File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/ssl.py", line 229, in sendall v = self.send(data[count:]) File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/ssl.py", line 198, in send v = self._sslobj.write(data) socket.error: [Errno 32] Broken pipe Cannot run aws.push for local repository HEAD:

I have another elastic beanstalk app that is running and when I run eb push in that directory it works fine so I dont think its anything to do with ruby or other dependancies not being installed. I also made changes and made another commit with a very simple message to make sure that wasnt causing the problem and still no joy

the difference between the app that can be pushed and this one is the aws account. the user credentials for this elastic beanstalk app that wont push are admin credentials
