AddrInUse

This error happens when figmaid is trying to bind a port that is already in use by another program.

Solution

1. See what program is using the port

   • sudo netstat -ltnp | grep '18412'
   • If you don't have netstat you can replace it with ss, the output will be a little different.

2. Kill the program

     0.0.0.0:*             LISTEN      70793/figmaid
                                       ^pid  ^process name
   

   • With process name: pkill -e figmaid
   • With process ID: kill 70793

For services you can forcibly stop the service by running above commands as sudo, but stopping the service with sudo systemctl stop <process name> is recommended.
