I am trying to interact with the text api to a lightstreamer server. I am following the doc pretty closely in instructions and for some reason I only get SYNC ERROR back. I can create a session fine, but the session can't seem to be used anywhere. Example:

Code:
http://.../lightstreamer/create_session.txt?LS_adapter_set=PROXYTELEMETRY&LS_user=


OK 
SessionId:S7e4020da06345760T4719431 
KeepaliveMillis:5000 
MaxBandwidth:0.0

# Next request:

http://.../lightstreamer/bind_session.txt?LS_session=S7e4020da06345760T4719431
SYNC ERROR

I don't have direct access to the server logs so I am not sure what this could mean. The docs suggest that this error is in response to a bad session id, but the session ID is coming straight from the create_session call.

Is there something I am doing wrong?
