This error says some other process already uses that port 1900.

For Windows users (case in question): See answer by Francesco Clementi.

For Linux users: Use netstat (part of net-tools package) to find out which processes use it:

netstat -tulpn | fgrep 1900

Then use:

ps -aux | fgrep <process name>

to figure out the process ID. Once you have process ID you can stop that process with:

kill -9 <ID>

Warning: this effectively kills the process holding that port, which may result in data corruption or loss, that is managed by that process. Proceed with care.

You have two solution.

first:

kill the process using that port with

netstat -ano | findstr :19000

taskkill /PID /F

the first command will give you a list of processes running on that port, then you need to get the PID and replace it on the second command.

second:

reboot your computer.
