Unexpected challenge(HTTP status code=407) received while
accessing HTTP proxy '%1' retrieving URI '%2'. This behavior differs
from the behavior recorded during test creation. For authentication
to playback correctly a challenge must be recorded during test creation.
Explanation
When the test was recorded, no basic authentication
was required on the proxy server. When the test is run, the proxy
server is requesting basic authentication information that is not
in the test.
System action
The request fails because authentication with the
server fails.
User response
Record the test again to capture basic authentication
information. Play back the new test, or add the basic authentication
information to the request in the original test.
