Failed to Bind Port Error

We have a video tutorial on Failed to Bind Port errors:


In rare occasions, a server is incorrectly assigned a port (the last 5 digits next to your server IP) that is already in use by another server. This will prevent the server from launching completely and will just attempt to restart repeatedly. 

You can check this on your server log by navigating to the console of your server's Multicraft panel.

Multicraft server console

You may have any of the errors shown below, depending on the Server Type you have selected. :

Sample 1:

[Server] WARN The exception was:$NativeIoException: bind(..) failed: Address already in use
[Server] WARN Perhaps a server is already running on that port?


Sample 2:

[Server] WARNING Could not bind to host /
[Server] INFO$NativeIoException: bind(..) failed: Address already in use


Sample 3:

[Server] INFO /usr/bin/docker: Error response from daemon: driver failed programming external connectivity on endpoint mc12345 (a9b8c7d6e5f4g3f2g1h0): Bind for failed: port is already allocated.
