Player in LAN suddenly can't find the server in LAN Tab

[Deus X Machina]

Five days ago, I used Maptool to show a Map to my players. All worked well, I tested it before, it was easy to start connecting, chosing the Lan Tab, and connecting to the server.

Yesterday the same procedure failed.
Whatever I did, i couldn't get the client to find the server.
It was still findable in the server list (but of course I couldn't connect that way).

I tested turning off both firewalls and antivirus softwares, but it didn't help.

I am using:
Windows 7
Maptool 1.3.b91 (on both Pcs, from a downloaded file)
Java 7 Update 67


I tried finding something in the log file, but all the timestamps date half a year back.

I don't think I installed anything in these 4 days, and I also didn't change anything on the router in these days.

I CAN connect to myself with a second started maptool.

You can try a direct connect by putting in the ip of the server along with the port number.

The nature of this failure is unclear.

You're saying that your server was "findable in the server list" but the client "couldn't find the server"?

Yeah half my players cannot see my server on the lan tab so either manually enter the ip or go out the router and then back in...

I meant, that it was in the internet Server list, but not visible in the Lan Tab

Meanwhile, I have solved the issue, and for Reference i want to leave the problem in my case here:
My Router did not establish / keep / connect / ... whatever the Local Network. i have no idea why that happened. I had a printer problem too, thats why I noticed it. and a restart of the Router (That also connects to the net) solved both issues.
I didn't even think, that the Router could put me through to the net, but not connect all the things locally.

I had a linksys go bad on me and do the same thing.

I've had something similar happen to my wireless printer "disconnecting" from the network. In my case I think it might have had something to do with the order of engagement after a power outage.
