I made a Minecraft server yesterday and everyone was on and could play but today I started it up and people got on. but then they could not get on but I was able to get on. I've restarted my router/ computer. checked to see if the port got closed it is still open and I've tried messing with windows firewall and reinstalled java. I don't even know the problem I've looked at everything I've also looked on a website to see if the server is open to the internet and it shows it is open.
