If there is an error in data being published to the Portal (e.g. email addresses), the following error may be encountered:


An error occurred while receiving the HTTP response to http://<address>/Services/DataPublishing.svc. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down).




This could be due to if none of the cyphers configured in SCHANNEL on the client side are supported by the certificate.

 Please make sure you have the right cyphers enabled at the SSL/TTL level.
