Problems with installing the Mirror new

 @hakupapa said in Problems with installing the Mirror new: Error: listen EADDRINUSE 127.0.0.1:8080 It would appear that something else is using port 8080 which MM needs

 Thx for the answer. I attempted a little bit and I found the problems. 
 The biggest problem was the new but cheap 128 GB card. I had also problems while starting. That seems to be also the problem for other Installations.
 The error in my first thread is not important. I used another smaller sd card and I got the error too but the mm works allright. So the problem seems to be solved.

 I got the same problem. Before the update i had a MM with three extra modules, namely: 
 MMM-AssistantMk2
 MMM-NotificationTrigger
 MMM-HotwordI also had teamviewer installed. 
 Everything worked fine.
 I had the update message an i did the git pull && npm installDidn’t had any updates during the update. 
 After the update i tried to start the mirror the normal way and i got the error like it’s mentiont at the beginning of this topic.What’s causing this and how to correct it?

 Usually that case is caused by multiple execution of MM. 
 “pm2 stop mm” then “pm2 start mm” Or just reboot.

 thanks for the reply.
 I don’t use pm2, i’m starting the mirror with “DISPLAY=:0 npm start”To be sure i tryed the “pm2 stop mm” but like suspected i’m getting the “bash: pm2: opdracht niet gevonden” message.

 Your comment about multiple executions of mm got me thinking.
 before the update i started the mirror. “pm2” didn’t worked and the mirror was shutdown, through ctrl+c.So i did a restart of the pi and… now it works :-D So the sollution (for me in this case) was restarting the pi, so it forgets the instance of mm :-D
