Dedicated Server Disconnected: Timed Out

Hello All,

we just set up a new Server on Win7 (before we had tried the Linux Version). (Linux works fine but was difficult to maintain so we switched to Win)

Der setup run fine and the RCON connection is also good. The Server comes up in Rust Game at Servers w/o issues.

But if you try to connect always you are “disconnected: timed out”.
Sometime you get online for 10sec or even a few minutes and then be disconnected but normally you get these message and disconnect during loading.

Does anyone have an idea?
We opened the ports for Rust 28015-28016 so it s fine so far.

Still not playable.

And we checked it before installing Oxide and after, both have the same issue so no Oxide Problem.

Thx for help!
