Your windows firewall Rules may be blocking it. (as there were many TCP connections to that machine in a very small amount of time).

It was working perfectly for 2 days. Now I cant get anyone to connect.
Error, connection:timeout
My port is still open, its not blocked in the firewall.
canyouseeme.org says it's closed. port (25565).
Need help as soon as possible please.

Sometimes peoples ip addresses change.

Go to CMD--->Ipconfig

See if its changed. if so just edit your portforward. Your other IP adress that people connect to will of also changed so you might have to change your minecraft server text document at the bit it says Server IP to your new changed one.

Get back to me if the problem persists.

Ok.

In the txt document in your minecraft server folder under server ip, what ip have you put down? The one i CMD, or the one you found on a site like Ip Chicken?

All that is going to show him is his local IP? Of course no one from outside his home network will be able to connect to his local IP. He will have to use his WAN IP, which will not change

At what part did i say to tell people his ipv4 address? He knows which one to tell people as hes had people connected to his server before. If you're going to try and prove me wrong, at least put something on post as its basically pointless to him.

Edited the post before to make it more clear.
