This has nothing to do with kp49 or CSSU the error is there for EVERYBODY. There is nothing wrong with anybody's device or Qtirreco installation, the server which hosts the remotes is just no longer reachable. The server has either been taken down or moved. The server location I think is hardcoded into Qtirreco, I couldn't find any documentation on the server or if it's possible to host our own or make it local to the N900.
