When trying to load into my own private server i have this problem, over my my server too.
I find the server in browser, enter password and the game enter the loading screen - the bar loads about half way and then cuts to a picture of my player - around 90 seconds later i get the error messege.
Kicked from game [time out]
all of my Alt accounts have the same issue, i spoke with nitrado who i rent the server with and they couldn't help.
they tried a hardware change - and told me to re-instal the server, this worked as i was able to log in.
but it didnt last long as i have this same problem again - i am unable to play on my own server!
please help.
