Try the steps below when you just can't find a reason for crashs.

1. Restart your computer and try it again. Most problems are fixed this way!
2. Reinstall Unturned Server Organiser.
3. Reset USO's registry and configuration by..
   1. Press Win+R and type in "%appdata%" click ok and delete the folder "UnturnedServerOrganiser3"
   2. Press Win+R and run "regedit.exe".
   3. Navigate to "HKEY_CURRENT_USER\Software\" and delete "Unturned Server Manager".
4. Fix your .NET Framework with the official tool from Microsoft

If you create a server using USO you create a LAN-(Local Area Network)Server. So your server is only available for players that are playing in the same network as you. If you want your server to be a public one you need to port forward. So this may be the most difficult part of creating a server. If if does not work just read this section again. (carefully!)
In general there are two ways to open (forward) ports with USO:

1. Automatic port forwarding
   
2. Manual port forwarding
   

If you opened your ports. Your friends can join with your external server ip.
Your IP is: 34.229.24.100

Unturned Server Organiser is able to open ports automatically. We are using a technology called UPnP (Universal Plug and Play) to access your router. Some routers are not supporting UPnP and sometimes UPnP is disabled by default. If it's not working you have to port forward manually.
You can enable and disable automatic port forwarding in the server panel.

If you don't like to use automatic port forwarding or it simply does not work you can manual forward your ports. There is no general solution to do that because every router is a bit different. You will find your solution by just searching "open ports <your router model>" in the web. You will have to open the port you set in the server settings and the next to ports above the port you configured.

For example:
If you configured 27015 in the server settings. Then you will need to open 27015, 27016 and 27018 in your router.

All ports need to be opened for UDP and TCP.

If you host the server on the same computer as you are trying to connect the server will always appear in the 'LAN' section. That's because the 'Internet' section stores external ip addresses and you cannot connect to a computer in your LAN with its' external address.
If you are not playing in the same LAN as you are hosting your server it will appear in the 'Internet' section. (provided that you opened your ports)

If you host your server on the same computer as you like to play Unturned you will need to connect via "localhost" or "127.0.0.1".

There are several reasons that can cause this kind of problem. The most often reasons are:

• Your computers cpu is overloaded. You can check that by running the Task Manager in background so it can frequently check the cpu usage during connecting to your server / playing on your server.
• Your internet connection is too slow. If you are connected via WiFi you should consider to use a LAN cable to connect to the internet.
• Sometimes there are mods or plugins that are outdated. Make sure all mods and plugins are compatible with the current version of Unturned. If you disable / remove all plugins and mods and the server does not kick you anymore then you known there is at least one outdated plugin / mod.

Since port forwarding is a thing that differs between nearly all routers, that's a thing you have to figure out on your own.
The way how to do it might be different even by comparing two routers from the same manufacturer.
In most cases there are video tutorials that you can use for your router.
Sometimes you can also find good texts that explain how to do it.

If you are 100% sure your forwarded your ports correctly but people still can't access your server please make sure you checked the following:

1. Make sure your computers firewall is not blocking connections on the servers ports.
2. Make sure your anti virus allows "Unturned.exe" for in- and outbound connections.
3. Possible but very rare your internet provider might not allow public connections to your network. If this is the case, you can't do much to get ports opened to the public.
