Calendar issue with 2.7.1

@sdetweil
Thanks for your comment.
First I changed the port as recommended in mm/config/config.js to 8081 and gave it a reboot.
After reboot and logon I checked the network connections by sudo netstat -lnptu:

pi@raspberrypi:~ $ sudo netstat -lnptu

I am surprised to see Electron already listening on port 8081, though I have not started the MagicMirror.
In the next step I launch Magic Mirror by calling: npm start &

Unfortunately I see again a EADDRINUSE message (port 8081):

MagicMirror will not quit, but it might be a good idea to check why this happened. Maybe no internet connection?

While the mirror is running I execute again sudo netstat -lnptu and get:

This is strange. The launch of the mirror npm start & tells me a multiple use of the port 8080 or 8081 (whatever it set in config.js) but netstat -lnptu does not know anything about a duplicate use.

As advised I also added below line right after if (event.type === “VEVENT”) { in ftp://192.168.178.36/home/pi/MagicMirror/modules/default/calendar/calendarfetcher.js

console.log("have event title="+event.summary);

Unfortunately the console outcome again is: “EADDRINUSE”

@drfukc is mirror starting on boot with PM2?

go to console and do

pm2 list
is something, get its name and pm2 stop name

drfukc

Thanks for your advise. After launching the mirror I do a pm2 list with the following result:

pi@raspberrypi:~/MagicMirror $ pm2 list
+-------------------------------------------------------+
¦ Name        ¦ id ¦ mode ¦ status ¦ ? ¦ cpu ¦ memory   ¦
+-------------+----+------+--------+---+-----+----------¦
¦ MagicMirror ¦ 0  ¦ fork ¦ online ¦ 0 ¦ 0%  ¦ 2.5 MB   ¦
+-------------------------------------------------------+
 Use `pm2 show <id|name>` to get more details about an app

With this information I stop the MagicMirror by the following command: pm2 stop 0

pi@raspberrypi:~ $ pm2 stop 0
[PM2] Applying action stopProcessId on app [0](ids: 0)
[PM2] [MagicMirror](0) ?
+------------------------------------------------------+
¦ Name        ¦ id ¦ mode ¦ status  ¦ ? ¦ cpu ¦ memory ¦
+-------------+----+------+---------+---+-----+--------¦
¦ MagicMirror ¦ 0  ¦ fork ¦ stopped ¦ 0 ¦ 0%  ¦ 0 B    ¦
+------------------------------------------------------+
Use `pm2 show <id|name>` to get more details about an app

By surprise the running MagicMirror survives and I kill the Electron instance with kill
After the MagicMirror instance is terminated I relaunch MagicMirror again with npm start &
The funny thing is that the naughty EADDRINUSE message is gone by now, but the calendar is still not working:

pi@raspberrypi:~/MagicMirror $ npm start &
[2] 1279
[1]   Fertig                  npm start
pi@raspberrypi:~/MagicMirror $

OK, as said above I have relaunched the mirror by npm start & and try to evaluate what is going on with pm2 list:

pi@raspberrypi:~ $ pm2 list
+------------------------------------------------------+
¦ Name        ¦ id ¦ mode ¦ status  ¦ ? ¦ cpu ¦ memory ¦

¦ MagicMirror ¦ 0  ¦ fork ¦ stopped ¦ 0 ¦ 0%  ¦ 0 B    ¦
+------------------------------------------------------+
 Use `pm2 show <id|name>` to get more details about an app

It’s funny, pm2 list tells me that the Mirror has stopped, while it is still running, but I still do not recieve any Calendar updates.
What is wrong here?

@drfukc that calendar,

url: "webcal://www.calendarlabs.com/templates/ical/US-Holidays.ics"

is thru 2018…

this one contains thru 2019

@sdetweil
Thanks a lot, - this helped :-) , it is so much easier if things are done right straight from the beginning :-D

In addition I also found the root cause for above reported “EADDRINUSE” error.
Simple again: I have enabled MagicMirror autostart in /home/pi/MagicMirror/installers/mm.sh, but don’t see it since I use a Remote Desktop connection (RDP) that gives me a different X-Window in comparison to the native Raspberry desktop.
Now launching Magic Mirror a second time on a different desktop and the same port causes the issue.
Since I disabled MM autostart Magic Mirror boots up without these errors.
Maybe I should get back from XRDP and switch to the preinstalled VNC to avoid having multiple desktops.

Again, thanks a lot for your support :-)

@drfukc I ssh to my mirrors… one autostarts, one does not…
