Windows 7: TCP/IP disabled

Hey, i run a server on my computer and everything was working fine until last night, ppl where playing and after a while everyone go disconnected.Now it looks that ports have been closed or something else weird because ppl cant join even i cant join.Yes ports are open i havent touched anything it just went down.I tryed different ports even my minecraft server wont work anymore. The error console gives me on connection is



WARNING: UDP_OpenSocket: port: 27015 bind: WSAEADDRINUSE
NET Ports: server 27015, client 27005
Could not get TCP/IP address, TCP/IP disabled
Reason: WSAENOTS

Someone said i could be hacked :/ I have no idea, so anyone have any suggestions?

Before I started digging through tons of stuff, the first thing I would do is completely reinitialize the system, shutdown everything, modem, router, computers, server.

Then restart and see if the issue is still there.
It could just be garbage data stuck in the line buffers.

I restarted my router and for some reason its working like before :/ Im getting new broadband today so i tought it could be that something changed but then i tought this happend in the night. Should i be worryed about that i could been hacked? All my server and everything seems to work like it did before

No it was likely just as I said, garbage in the buffers.
It happens especially when a connected device is left running uninterrupted for an extended period of time.
Which is generally true of both routers and modems.

Ah i see Glad it was such a simple problem. Thank you for your time and help, have a good day
