My friend can't connect to my server

[FilipSebik]

Hello, I want to play Minecraft with my friend but it always says: Connection Timed Out. When he tries to connect to my server. 

Things we tried: 
Allowing java, javaw and ports 25565 for TCP and UDP in firewall (on his PC too).

Portforwarding, using Hamachi or Zerotier and neither of them worked.

Restarting our PCs

I changed the IP in the server config to corresponding IPs to the apps or even blank sometimes

Turning off online mode and turning it on changes nothing

Disabling firewall is not an option because I don't want to and neither he does.

Everytime he wants to connect it just says that: "Player has joined"

and after like 20 sec it says: "Connection Lost: Timed Out" 

"Player has left the game"

 

I am able to connect to my server

 

Both my and his internet connection are fine but it seems that I can't ping his IP *Hamachi, Zerotier or his Public IP

 

He has LTE internet using a router and that router has a setting named SPI Firewall. If that is the case then he can turn it off because every PC has a firewall.

I have DSL internet. I have played with other friends using my server but it doesn't work with him

 

Does anyone know how to fix this issue? Thanks for help

Are the ports forwarded on your router?  Is your router getting a proper public IP address or a private CG-NAT address?

Yes it is. The port is the same 25565 and I tried public IP and the one that my router assigned which is x.x.x.12

The first two digits are the important ones to tell.

What else than the usual 192.168 /24

[Alex Atkin UK]

Those are the LAN address, what I was curious about is your WAN IP actually reported by the router itself.

 

Also have you made sure your PC has a static IP address (ideally static DHCP in the router) as otherwise it can change each time you boot up, causing the port forward to point to the wrong IP address.

192.168.xx.xx is your local address. Your friend can't connect to that unless you are on the same network. What you need to tell him is your public IP address.

Static DCHP set in router as well as in my PC

You mean the Public IP from https://www.whatismyip.com/ ? If that then yes I used that too

[Alex Atkin UK]

No the router itself, as if you are behind CG-NAT then that site will still show the public IP your ISP is routing you through, its not necessarily what your router is being assigned.

 

I'd be tempted to install something like a web server on your PC and port forward to that too, see if your friend can access that to test if the port forwarding is working or not.  Its pretty hard to be sure with games.

Oh well, where the hell do I find that address?

@Alex Atkin UK summed up pretty well. Isn't it much simpler to find a free Minecraft server hosting site? Yes, they are limited to 5 or 10 players, but that's still too much for you and your friend. 

[Alex Atkin UK]

Look around in the router, I'd expect it to be mentioned somewhere.

You mean the minecraft servers that nobody play on and are usually 0/10 everyday or the free ones that are Hourly instead of Monthly which is a term that I don't understand

Actually even in the deepest darkest corner of my router settings, I didn't find anything close to that

[Alex Atkin UK]

Have you tried something like https://www.grc.com/shieldsup putting your Minecraft server port into the custom port section?

Hang on a bit, isn't this whole thread about your friend not being able to connect to your server? Which, to me, means that you want to play Minecraft with your friend on your server. So what is wrong with a free server with a maximum of 10 players if only you and your friend are going to play on it? Since you do know that you can not host Minecraft servers at home without static IP address which costs around $100 per month.

Yes, I want to play minecraft with just him but it doesn't allow him to connect for some reason and other friends could connect when I played with them (it was like 1 year ago)

That website looks like it wants you to read it to use it which I don't like so no I didn't

How do you expect to do something if you didn't inform yourself about it or at least read the tutorial on how to do it? Imagine if I went on to create a car, but was too lazy to read how do you make cars, study aerodynamics, mechanical engineering etc. Would that car work? Definitely no. Also, one thing working 1 year ago doesn't mean it still is and does work. Maybe your ISP changed something about your network, or you changed your router, updated firmware, heck Minecraft changed something.

 

I'm seriously confused. You want to do something but can't read a website tutorial which could potentially solve your problem.

They don't need a static IP so long as they can find out what their current IP address is before each gaming session and tell their friend, or use a dynamic DNS service.

 

Which makes me wonder now, are they actually telling their friend to connect to their public WAN IP address or their LAN one?

True, although that means the host has to have constant access to their PC to check their current IP address, which is kinda crap because maybe some friends want to play in the middle of the night, or he's not home etc. Dynamic DNS service is well nice, that's a great solution.

Actually you made me use that site and it spit out this 

Stealth

Unknown Protocol for this port Unknown Application for this port

 

It could be Open, Closed or Stealth... 

 

I depend on intuition and if I think something won't work, 90% of the time it won't and this time it was the time it didn't work

Public, LAN, hamachi and Zeropoint ones each time I changed the setting

I am not hosting 24/7 for my friends. If we are online and we agree to play together, I will fire up the server and we will play and it goes down as fast as we end the game

That's a really interesting situation you have there. Do you mind sharing your router model? Also, have you tried asking some of your other friends if they can connect? It could be a security thingy not allowing your friend to do it.

No other friends have their minecraft accounts anymore because they forgot the password so no I can't

[FilipSebik]

Uninstalled old Java versions (almost broke down and reinstalled my windows cuz java BS)

Installed new java version and tried older minecraft and it works

 

So the solution is that newest minecraft has some sort of BS thing that disallows players to join
