I host my server from my own computer with forwarded ports. I have checked everything on my side and I cant seem to figure out what is causing this issue. When I run the server and try to connect in game I am faced with this error message after a minute of it trying to connect:

Connection error: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

I've tried running a fresh server setup, updating my client and server, checking the ports, checking my firewall, but I just cant seem to figure out what is causing this issue. I'll also point out that in the host console I am not getting any messages that indicate anyone has tried to connect or join the server. So it seems the request is getting stopped somewhere before my server catches it.

I am having the same issue.. I have a friend connected to my local server that is being hosted on a dedicated machine, but I cannot connect from inside my local network from a different machine.
I try Internal and external (public) IP, and neither of them work.
This is really annoying as I can sit here and watch my friends play on my server, but I can't connect.

Other servers seem to work fine. This is the same error message I get weather or not the server is even running, so something tells me it solely a server side issue. My main confusion with this issue is that my server worked just fine up until recently. I've double and triple checked simple things like IP and correct ports, but cant seem to find an issue there.

In the end, with what I've found I would understand if we were unable to find a fix for this issue, mainly with it being so vague, but if anyone has any ideas I would be glad to hear them.

Upload your KSP.log to pastebin and link it here.

There are too many parameters to check. Do other kinds of servers work?

Sorry for the wait, had a busy weekend.

Here is my KSP.log: http://pastebin.com/aLmExkcn

(And yes I know two of my mods are out of date, specifically KAS, MechJeb2.)

According to your log, you tried to connect to a server with the IP address 99.187.145.8.

When it worked, were you trying to connect to it from outside your LAN? If it's correctly port-forwarded, and you try to connect to that 'public' IP address from another machine outside the server's LAN, it should work. But if you try that address from a computer inside the same LAN that the server machine is on, it won't work. I might be completely wrong, but this message could be DMP's way of saying, "Hey, I'm inside the LAN. I can't connect to it using its external address."

Good luck!
