Troubleshooting Concurrency Issues

This section provides errors that you may encounter when using the concurrency feature as well as possible solutions.

• The server was unable to process the request due to an internal error
• There was no endpoint listening at http://<machine>:<port>/CobraWebService/service that could accept the message
• The encryption type requested is not supported by the KDC

Note: There are additional steps that you may need to perform when implementing concurrency:

• Before installing an update, back up the *.config files.
• If you are using the Cobra installer to perform an upgrade of a machine with the Cobra Gateway Service, stop the service before installing the update and start it afterwards to avoid having to restart the machine.
