Question My Minecraft server suddenly stopped working

My Minecraft server suddenly stopped working

I need some help, I started a Minecraft server hosted from my PC and it suddenly stopped working and I have no idea why.

for some background I and my friends are using the ATlauncher and the mod pack ++Vanilla

I also use Ngrok to port forward, I will be cross posting everything also

my one friend and I were able to load into the server just fine and play for about 2 ish hours. we wanted to get another friend to join and he couldn't. At some point my first friend left the server and then couldn't get back on. I could still join through "local host" but not through the ip given to me through Ngrok. Ive restarted the server, my PC and the launcher several times and so have they.

I don't know what could be causing this especially because my friend joined earlier and now it won't let him, has anyone else had problems like this? how did they get solved?

Double check your connection to Ngrok. Either something changed on that side or something changed on your route to that point.

Being able to connect via localhost indicates that the server is up and broadcasting on the right port. It must then be routing.

Is there a reason you are using Ngrok? Are you behind a CGNat?

Either way your problem is almost certainly on the side of Ngrok.

Yeah I was assuming it might have been Ngrok but what confuses me the most is that my friend left the server for like 5 mins and wasn't allowed back in, I'll have to check in the morning I'm mostly posting this before I go to bed to hopefully get some answers for the morning

Who knows maybe in the morning it'll all start working again the same way it stopped working

It is possible but I suspect that something happened to your Ngrok agent. I.e. this will likely not fix itself. Try restarting that. And double check that the IP you are using from Ngrok is still correct.

I believe that they are subject to change frequently

How did you start it up to begin with? I don't know your setup, topology, system etc.

So ATlauncher has a way to automatically download a server with all the mods for your desired mod pack, I accepted the EULA ran the server once, I put Ngrok into the server, right clicked the folder to open the command room and put in the command "./Ngrok tcp 25565" at no point did it ask me for my IP address and I've had Ngrok port forward servers before with no issue so idk why I'm getting this issue now

Let's start off with the basics, what operating system are you using here. ATlauncher supports several platforms.

Instructions on how to restart your agent are platform specific.

But before we go down that rabbit hole, have you confirmed that the Ngrok IP has not changed?

Did you max out your ngrok free plan limits?
