Server not found/Communication error

[grmand]

Ok so here is the problem...

 

We have been running a server pretty much non stop for 6 weeks. Everyone can log in. No real lag to speak of and all of a sudden no one can log in. Can't find server or Comm error. 2 of us are in the same house on the same LAN, can't even log in on the computer the server is running on. When you can it is brief and you fall or you get about 10 seconds frozen and then get kicked off. Sometimes you see the server but when you click on it to join, you lose connection. Can't reach server.

 

We have checked:

- Server is current 3.1.2

- Technic launcher has same version of Tekkit classic

- Firewall setting have not changed on Server or Modem

- No new programs installed.

- Can connect to a local single player world no problem

- Deleted and reloaded both Launcher, Server and reset the pack on every computer with no results.

 

What can we check next. All I know is 'lag' is most likely diagnosis but that doesn't cover why you can't log in on the same computer as the server to the server....

 

Any suggestions would be really great, thanks.

 

Any info I haven't included just ask...

Well there's no issue with wireless/ports since it's an ethernet connection
Does the server box stay online all the time even if you can't access it?

I do reccomend you check your FML-latest.log and latest.log in the 'logs' directory(folder) and post them to pastebin.net so I can help diagnose any problems with the client.
