MMM-Caldav not listening on port 8080

[peterpan894]

Hi,

I have a problem with MMM-CalDAV that it seems it is not listening on port 8080:

sudo lsof -i -P -n | grep 8080

does not return anything, however the calender seems to be fetched from my owncloud server:

[13.11.2023 09:39.26.779] [LOG]   [CALDAV] calname(calname.ics) has 13 events
[13.11.2023 09:39.26.786] [LOG]   [CALDAV] calname.ics is refreshed.

The log output shows:

[13.11.2023 09:17.13.712] [ERROR] Calendar Error. Could not fetch calendar:  https://localhost:8080/CALDAV/calname.ics TypeError: fetch failed
    at Object.fetch (node:internal/deps/undici/undici:11372:11)
    at process.processTicksAndRejections (node:internal/process/task_queues:95:5) {
  cause: Error: connect ECONNREFUSED 127.0.0.1:8080
      at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1555:16) {
    errno: -111,
    code: 'ECONNREFUSED',
    syscall: 'connect',
    address: '127.0.0.1',
    port: 8080
  }
}

the ics file is physically present:

ls -al modules/MMM-CalDAV/service/

drwxr-xr-x 6 peter peter 4096 Nov 13 09:11 ..
-rw-r--r-- 1 peter peter 2570 Nov 13 09:39 .calname.ics

The configuration from the MMM-DavCal is

{
   module: "MMM-CalDAV", 
	config: {
		timeRangeStart: -30, // Get events from 30 days before
		servers: [
		{ 
			name: "calname",
			envPrefix: "OCLOUD_",
			serverUrl: "https://myserverurl/remote.php/dav/", 
			calendars: ["calname"],
		}
		],
	}
},

The configuration of the calendar module:

{
	module: "calendar",
	header: "My Calendar",
	position: "top_left",
	config: {
		calendars: [
			{
				fetchInterval: 7 * 24 * 60 * 60 * 1000,
				symbol: "calendar-check",
				url: "http://localhost:8080/DAVCAL/calname.ics",
				auth: { 
					user: 'user1', 
					pass: 'password1',
					method: 'basic'
				}
		   }
		]
	}
},

The content of .env:

CALDAV_SERVICE_USERNAME=user1
CALDAV_SERVICE_PASSWORD=password1

### For Owncloud
OCLOUD_username=oc_user
OCLOUD_password=oc_password

I have tried a lot of things but i guess the main problem is that MMM-CalDav is not listening on port 8080? Running magic mirror as root does not help. MagicMorror runs on a raspberry pi 4 but only the server part

npm run server

If i use another calendar it works:

https://ics.calendarlabs.com/46/d26011d3/Germany_Holidays.ics

Can anyone support here?

Thanks,
Peter

@MMRIZE , found the issue, you last sentence solved it, i was indeed running the server on port 9090 but I set the url of the calendar to 8080.

After changing the port of the calendar url to 9090, all is fine.

Thanks for your support!

@peterpan894 the local calendar should be

http://localhost:8080/CALDAV/calname.ics

you have

https://localhost:8080/CALDAV/calname.ics

note the httpS

[MMRIZE]

@peterpan894
You can test whether iCAL is serving or not by yourself.

1. Execute MM
2. In the same client ,
   open the browser then navigate to this.

http://localhost:8080/CALDAV/calname.ics

@sdetweil
He seems to set http scheme properly in the config he posted.

symbol: "calendar-check",
url: "http://localhost:8080/DAVCAL/calname.ics",

Maybe a ipWhitelist setup could be the issue.

[sdetweil]

@MMRIZE but the error says

Could not fetch calendar:  https://localhost:8080/CALDAV/calname.ics

so at least that config used https

[peterpan894]

the https was a typo. The ipWhitelist looks like

ipWhitelist: []

that should be fine. I do not have a desktop on the rpi so checking on the same client is not possible.

Must there not be a listener on port 8080? In my case there is none. I have also no idea how to debug, even with all logs on, there is no aditional information except for:

[13.11.2023 22:19.31.680] [ERROR] Calendar Error. Could not fetch calendar:  http://localhost:8080/CALDAV/wielens.ics TypeError: fetch failed
    at Object.fetch (node:internal/deps/undici/undici:11372:11)
    at process.processTicksAndRejections (node:internal/process/task_queues:95:5) {

      at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1555:16) {
    errno: -111,
    code: 'ECONNREFUSED',
    syscall: 'connect',
    address: '127.0.0.1',
    port: 8080
  }
}

I tried with Curl:

curl -v http://localhost:8080/CALDAV/calname.ics
Trying 127.0.0.1:8080...
connect to 127.0.0.1 port 8080 failed: Connection refused
Failed to connect to localhost port 8080: Connection refused
Closing connection 0
curl: (7) Failed to connect to localhost port 8080: Connection refused

The only thing which can be the cause is that i run

 npm run server

can someone check on a working system if there is a listener on port 8080? I can only excecute the server as i have a headless system

Thanks

@peterpan894
Could you post this to issue board or discussion of GitHub repository? I should look inside with focus. And maybe needs to talk more closely.

Ah, you may run the server and client on different devices.
“localhost” points a device-self, so “localhost” in client will be different from that of server.
Use IP address of server instead of “localhost”

[peterpan894]

I tried 127.0.0.1, 192.168.x.x, same result. The curl was excecuted on the same machine the MM server was running

[sdetweil]

@MMRIZE if the node_helper depends on info sent down from the modulename.js, then it will not happem as that runs in a browser…

so @peterpan894 one thing to try is to open the MM server in a browser
then see if the port is open
