Calendar randomly stops updating itself

[outlying]

Hi, I will start with I’m on 2.20.0 version of MM but this issue is bothering me for a long time so, the problem is … calendar randomly stops updating itself, I see mirror, and every other module is updated (date/time, weather, news, etc) but, for example, right now calendar is showing me, on its first position, event which ended yesterday (almost 24h ago).

Sometimes I realize that the calendar is not working because the calendar event I added is not appearing on the mirror display.

Configuration is not very complicated and it is working (if I restart MM), for obvious reason those are not full Google calendar URLs

 {
                        module: "calendar",
                        header: "Kalendarz",
                        position: "top_left",
                        config: {
                                maximumNumberOfDays: 31,
                                showLocation: true,
                                wrapEvents: true,
                                timeFormat: "absolute",
                                fetchInterval: 120000,
                                calendars: [
                                        {
                                                symbol: "calendar-check",
                                                url: "https://calendar.google.com/calendar/ical/"
                                        },
                                        {
                                                symbol: "calendar-alt",
                                                url: "https://www.thunderbird.net/media/caldata/PolishHolidays.ics"
                                        },
                                        {
                                                symbol: "rocket",
                                                url: "https://calendar.google.com/calendar/ical/"
                                        }
                                ]
                        }
                },

Usually, I restart MM but thing keeps bothering me

@outlying Just for assurance:
The calendar URLs you’re posting are the real ones or just abbreviated for privacy here?

[sdetweil]

@Fozi he said they were not actual.

[sdetweil]

@outlying can u tell us about your environment?
I think if there is a fetch error, it’s not recoverable…

u might be able to see this in the startup console if u change the config.js logLevel like this

logLevel: ["INFO", "LOG", "WARN", "ERROR", "DEBUG"],

and start mm with

npm start > somefile.txt

(so u need to stop mm if using pm2 )

[Fozi]

@sdetweil Yeah, I see… When I setup calendar quite some time ago I remember that I had some trouble, too.
What I did -I cant’t remember why because it is undocumented- was to change
from

timeFormat: "absolute",

to

timeFormat: "HH:mm",

That is a shot in the dark, but might help, too.

Sure I will respond with the results in a couple of days but I moved to another apartment and my mirror is not yet running (I hoped it will not take that long).

But the problem with logs is, that it might take a couple of days, usually, after the restart, it works fine for a week or two, maybe more, and suddenly stops.

[sdetweil]

@outlying ok, that sounds like a networking problem, causing an error and never recovering

I have noticed the same thing, or rather my Ma has on the one I made for her. Some times the news won’t update until it power cycles again. If nothing bad happens to the breaker sometimes will display same news from a month ago.
