Problem

When running the crucible.py script to create a review, the script returns the following error in the command line output:

1 Eror executing request <FISHEYE URL> - [Errno 104] Connection reset by peer

Cause

There is a proxy between the client where the crucible.py script is run and the server hosting Fisheye, and the proxy is terminating the connection

Resolution

Review the network configuration in order to guarantee that the proxy does not terminate the connection.
