minecraft launcher could not connect to server 2017

Below that, you should see something like 'inet addr:' and then a sequence of numbers.

Mac: In Terminal, look for something called wlan0 (for Wi-Fi) or eth0 (for wired Ethernet).

Remember the sequence of numbers after that. Look for something that says 'IPv4 Address'.

Windows: Type 'ipconfig' in the box and hit enter.

Mac: Open up Spotlight Search and type Terminal.

I have gotten this problem before, and it's very easy to work around. I would have to believe that this port (UDP 4445) is the one that is being blocked from allowing the game to announce it self as a 'open server' locally. On searching about this, I've found a post from 2012 about a plugin author making an app to make local worlds announce themselves as LAN worlds using the same UDP 4445 'Announce' port. four new connections, two of them matches the port that the game reports (60xx), and the other two are UDP 4445 left unconnected. I've tested this on the other PC, with the same outcome. (Most likely this is to the Minecraft Process, except the red one which is Amazon's cloud services) When I click into the Multiplayer tab, we get four new connections, but two of them ( UDP 4445) are left open: What I've found that is Minecraft does not use it's own PID when making a network connection, but instead has Java handle the network calls.įrom my personal PC, Java opens and connects with 6010-6127 onto a process locally.

I've also installed TPCView on both machines to view the network connections they create and leave open.

I've setup two machines, with Minecraft on both PCs. So I've done some testing on my side on a Windows machine, and this should be the same on all systems from what I've seen online.
