Home minecraft server not Working

[Swepknight]

Hi,

 

I set up a home server (an old PC i5 4460 and 8GB DDR3) I wanted just to use it to host a Minecraft server, I've set it up and completed the port forwarding along with sorting out the firewall. The problem is that only people on my home network can join, When my Gaming PC is on a different network I get the error connection refused: getsockopt while when my mate joins the server from his network he gets the error connection timed out after 30000 ms: *server IP* . I have tried YouTube, Reddit and Discord I cannot figure this out, any help would be greatly appreciated! NOTE: I have a suspicion it's the firewall but I've set it up exactly like the video 3 times now so I don't know.

Update: The port is closed (port checker) however I have enabled it on my router and now I really don't know

Welcome to the forums!
I'd bet your ISP has NAT networking or whatever that thing is called. If so, You don't really have your own IP, you share it with a couple dozen other people. I got around that by getting a static IP from the ISP. Costs 5$ a month, but allows me to run a VPN into my network so super duper worth it IMO

First, make sure you are using your public IP address and not your local one.

 

Some ISPs block common port numbers, try changing to a different number.

If this isn't possible (ie your ISP just plain won't support it), you could also just spend the same money on a server from Linode or Vultr and run it on there.

I kind of just want to set it up myself because I'm a nerd, if I'm honest, and I want to play around with servers and stuff, so I'm trying to avoid hosting sites if I can. Thank you for your response.

Hi, My ISP port forwarding had me put both my local and remote IPs in, however, the server IP is my remote one. How would I change the port number must I just change it on my .properties file as well as on my firewall and go, on my way, or are there any other things I would have to adjust?

I was already Planning on contacting mt isp about any kind of blocking on their side, ill ask about this. Thank you for your response.

Well, you'd still be setting it up - you just wouldn't be doing the hardware. Linode/Vultr just give you a bare Linux server, it's up to you what you do with it.

 

I get it, though. I run a MC server on my home server too (as well as AI stuff etc).

 

Really, that was just a suggestion in case the ISP can't do it though - if everything's hidden behind NAT, then they won't be able to do what you're asking no matter how much money you throw at them. I had the same problem with a fibre ISP, ended up stuck with Virgin Media because they were the only other option in the area for synchronous gigabit (but at least port forwarding works).

Ohh that's actually kinda cool, the ISP solved it, but now it's doing some weird stuff I can't join my server locally, but can externally and I am losing my mind RN
