Server listing problem.

Hey guys aaomidi here, owner of NationCraft,
I currently have 3 servers, all of them were working fine, but the skyblock one was online but didn't show online @ the server list in your client.
I discussed the problem with many people, no one knew what was wrong.
One day I just told myself leme delete server.properties. I did that.
Then BAM the server showed up as it was online. This problem still exists for a lot of people... LIKE A LOT.
So I hope this helped.
1. Turn off your server.
2. Delete your server.properties.
3. Restart your server.
4. Edit your server.properties to your hearts content

Thanks for reading this and hope it helped

 

LOL. There no is reason that is the cause.
Minecraft handles the pinging poorly, so if a client tries to connect too many times it just closes the socket and says offline (also, many custom builds have a connection throttle.)

 

Well this worked for me
