BindToPort: EADDRINUSE

[Kappes Buur]

Years ago I played multiplayer with my colleagues at work, it was great fun.
Now my grandson is interested in making maps and playing me on multiplayer,
but I get this fatal error :

**** DIED WITH FATAL ERROR:
BindToPort: EADDRINUSE

While I used the ZDoom forum search for this error it was not helpful at all.
Is there a solution to fix the problem?.

Also, using the command

gzdoom.exe -join ip address

which ip address do I use
a. the ip address of the join computer
b. the ip address of the host computer

[wildweasel]

When using -join, you want to put in the IP of the computer that's hosting. on Windows, this can also just be the computer's hostname, if I recall, as long as you're both on the same LAN:

Code: Select all

gzdoom.exe -join DESKTOP-CVO38HJ

To get rid of the message BindToPort: EADDRINUSE I had to reboot the computer.
This happens when pressing X instea of Abort Network Game after trying to host a game.



However, the network session still does not want to work when I start to host with
gzdoom.exe -host 2 on my computer and
gzdoom.exe -join host_ip_address on the other computer

and somehow the host_ip_address is not detected.

I did get the host_ip_address from my router's computer name DESKTOP-xyz.



Checking on NorVPN I got a different ip addess



neither of them work for a netgame.

Is there a command in GZDoom 4.10.0 to identify the proper ip_address?

[yum13241]

You need to get your privateIP Address. On Windows, you can run "ipconfig" to find your private IP address. If you are on a LAN, you need THAT, not your public IP address, the one NordVPN is giving you. If you are not on the same network, NordVPN's IP is what you want.

Make sure GZDoom is allowed thru the firewall.

for future reference the EADDRINUSE error is usually due to gzdoom not having shutdown out of MP properly for some reason. You'll have to hunt down the gzdoom.exe program thats running using the task manager. restarting the PC would also kill any rouge copies of gzdoom running around since your restarting everything.
