Error code EADDRINUSE

[PXNDA]

I have just added MMM-Remote-Control but I started to get this error:EADDRINUSE. I am using a Windows computer.

I also found this error code in the logs ELIFECYCLE. I’m using Git Bash.

I cloned MagicMirror and copied the run-start.sh into the original but it still doesn’t work.

@PXNDA that means something is already using port 8080. Maybe u have pm2 running magicmirror already

[mumblebaj]

@PXNDA As @sdetweil mentioned, the EADDRINUSE means that something is already listening on port 8080. You need to check what it is and kill the process and try restarting the MM again.

[PXNDA]

Thank you. It fixed the error code but now it is asking me to create a config file when I already have one.

[sdetweil]

@PXNDA u have a syntax error

From the MagicMirror folder do

npm run check:config

Fix errors top down, rerun til no errors

[PXNDA]

Thanks it worked but I now have a black screen, with nothing on it.

[sdetweil]

@PXNDA open the developers console, ctrl-shift-i, select the console tab and scroll up to find any errors, usually in red text
