When installing Blueprint 5.x the initial Tracker and EDI web service tests fail with the message "The underlying connection was closed: an unexpected error occurred on a receive."
This error happens because SSL is enabled for the Tracker web service (where it is optional) and the EDI web service (where it is enabled by default and required). However, the server has not been enabled to support any cipher (TLS 1.0, 1.1, or 1.2; 1.2 is only available for Blueprint Enterprise 5.2 R1 Service Pack 3 or Blueprint Enterprise 5.2 R2).
The necessary ciphers can be enabled using Windows Registry.
From this point, the SSL-enabled web services will pass their tests.
