First of all could be a connection problem on both server and clients.
So please share with us your connection details doing a test using www.speedtest.net running a test using AMSTERDAM, NETHERLANDS (close to Lastplace server) and POZNAN, POLAND closest speedtest server to our nk server, in Berlin, and to the closest to your home.
Once you run the test use the "Copy Forum Link" on the results.
Are you using DSL or something else? WiFi or not?
