If you are using the Python client with the urllib3 Python library, you may get the error:
('Connection aborted.', RemoteDisconnected('Remote end closed connection without response'))
This is a known issue in the urllib3 library. See the related Python issue in GitHub: #4664 for more information.
If the Python client tries to send a request at the same time that the TCP connection is terminated, it incorrectly interprets the connection as 'closed without response'.
This can happen when lots of players are simultaneously trying to reserve payloads, which can cause transient network issues.
Retry the connection request as this normally resolves the issue.
If a retry does not resolve the problem, contact zeuz support.
