An Error Occurred While Receiving the HTTPS Response During License Activation

This article applies to the following products:

  • Messageware Admin Center
  • Messageware License Utility 



Error appears when performing license activation either from MAC or the License Utility when the organization's firewall/proxy has blocked license activation internet requests from server source. Adding the proxy values to the web.config of the MAC still fails to connect to activation.


Error messages pop-up when license key fails to be activated as the request never reach the activation URL.

(Note: Connecting to the activation URL from the server's browser is not a 100% proof that server has the ability to complete the license activation. Certain firewall/proxies can grant or block individual access to browser, application or ip address.)

Error received from the Messageware Admin Center:

An error occurred while making the HTTP request to https://client.messageware.com/mweaf/service.svc. This could be due to the fact that the server certificate is not configured properly with HTTP.SYS in the HTTPS case. This could also be caused by a mismatch of the security binding between the client and the server.


Error received from the Messageware License Utility:

Connecting to the Messageware Licensing Service ... FAILED

Error: An error occurred while receiving the HTTP response to https://client.messageware.com/mweaf/services.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).  See server logs for more details.


The activation requests use port 443 to https://client.messageware.com/mweaf/services.svc

To activate the license, the organization's network team can either:

  • Temporary allow internet access to the server where MAC is installed, which then can be disallowed again after the task has been completed.
  • Utilize the License Utility on a client PC with elevated internet access.
