UDP initialization failed.

If your server is running on your own computer, connecting via your external IP could cause weird issues. I've noticed this myself when I was messing around with that.

I worked around it by setting the server IP to 127.0.0.1, which would mean that if someone connects to the server they would be connecting to 127.0.0.1 instead of my real server. This was fine for me because I just needed it as a dev test server.

check your ports are open while running server. If not, open them.

Canyouseeme only tests TCP, btw.

I also had something weird going on :

Other people could join my server , I could not play on it trought the internet only local.

When trying to connect via NET it shows the "UDP initialization failed" error. Server starts just fine, ports are forwarded(checked with other game). Connecting via LAN works just fine. I hosted a server before and never had such problem.

I had the same Problem.

2350 TCP & UDP General, open
3450 TCP & UDP P2P, open

"Could not connect: UDP initialization failed"

In my case I fixed it by adding...

Code: Select all

<bind_ip_address>YOUR-SEVER-IP</bind_ip_address>
