No that shouldn't happen, I know sometimes it does when the server has a dodgy connection I've never had it but I've seen it drop players before like that. You will always have a message box if its an admin kick.
If it's a battle eye kick you'll get a message with a script restriction number let me know those because I can usually fix them. Other times it will be because of a signature check on your client not matching for files (can happen for various reasons) I think in these cases you don't see the kick message either but friends in game will.
On the upside I ordered our new server this weekend, I will be setting it up next week hopefully then connection issues like this will be gone for good
