Unable to read data from the transport connection: A connection attempt failed. - Keycard.

If we see the above message while genearting key from the eZee absolute software we need to check if the server IP and Port number of Encoder is not changed.


  1. Make sure that Server IP and Port number is same in eZee service, which we get from the hoteliers.


  1. These details should be provided by hoteliers or the Door lock Software Vendor.


  1. If they are not same, then we will be able to see the above message while generating key from the absolute software.


  1. We can also check once they give us correct details, with SDK and try connecting with the IP address given by the Hoteliers. If it is successful in SDK then we can add in eZee Services.


  1. We can restart the service and try generating key again from eZee absolute software, it should be able to generate the card without any error.




Above solution should be able to resolve the concern with, unable to read data from the transport connection: Connection attempt failed. We should be able to get success message if IP and port number is correct.
