If the Server is hosted at home it could be an bandwidth issue. The upload is always a limiting factor for servers. This can be tested like this: If the problem occurs the host alt + tabs out of the game. Open up the command console and type: ping -t google.com Wait a few seconds, close down the server, wait another few seconds. Do a screenshot of the command console and post it.

When did you upload the database? Before the first start by chance? If you start up a new "map" or for the first time the world.db will be overwritten.

My Server is running on Debian / Linux, dunno the exact version. I can look it up later on if you need that info.

The Whitelist worked for me. Be aware that the Password is case-sensitive. If you want to connect enter the needed Data and press save, before you try connecting. In the first try i forgot to save and could never connect.

Instead of a need to Reset, i would rather have an "Gamemaster" who could start an Event oder resupply/repopulate certain areas. Or maybe an automated feature which places new loot and zombies, if there is no activity for X in-game-Days.
