The response message:
The lock software server application has not established connection with the Mews Open API application. Make sure your lock server application is online. Read more here:
Why this happens:
In an integration between Mews and a door lock software using the FIAS protocol, Mews typically expects the door lock software to initiate contact with the Mews Open API application. This generally applies to Hafele Dialock, Messerschmitt, TLJ, and VDA.
This initial contact at start up is required in order for the two systems to establish and maintain a connection for exchange of all future key creation commands from Mews and processing of the responses from your lock software.
The Mews Open API application returns this error message when it does not detect the necessary message from your lock software to initiate the connection on the port number specified in the Mews Open API application.
How to resolve:
Make sure that both the Mews Open API application and your lock software server application are installed on the same computer
Verify that the port number entered in all three places are matching: Key cutter integration, Mews Open API application, and in your lock software settings
In your Mews Open API application, make sure that you have ticked “Enabled” under “Fias settings”
In your Mews Open API application, you should only select “Client mode” if you are using the Dormakaba lock software
Once you have verified that all fields have been completed correctly, restart your lock software server application
Sometimes it also helps to restart the computer.
