EADDRINUSE: address already in use 127.0.0.1:8090

[theaddies]

When I boot up the MagicMirror I will get a blank screen with a cursor. The message in the log is the following. If I simply change the port to anything else, 8080 then the mirror boots up fine. If I get the error I switch it back to 8090 and it goes away again. I have nothing running on the machine. It is a raspberry pi II with only MagicMirror. TIA

@theaddies that means something is using the port , maybe you have two instances of mm trying to run

do

pm2 status

are there 2 apps defined?

[theaddies]

@sdetweil Thanks for the reply. I think I did have 2 instances at one time, but I deleted the other one. It does not show up on pm2 status. Is there anything else to remove? Thansk.

[sdetweil]

@theaddies look for running processes

pm2 stop all
ps -ef | grep node

or

ps -ef | grep npm

[theaddies]

@sdetweil I found /usr/bin node serveronly.

is that the culpirit?

[theaddies]

@sdetweil I suppose this makes sense but I killed it and it immediately restarted. I don’t know how to remove it.

[sdetweil]

@theaddies you must have added it as part of the manual install instructions

do the reverse to take it out…

[theaddies]

@sdetweil thanks for the reply but I have no idea what I see did

[sdetweil]

@theaddies sorry. no idea myself.

I gave up long ago trying to remember the 900 different ways to auto start things on the myriad different platforms.
