Another No upcoming events MMM-Calendar

[Dennis-010]

Hey all,

For quite some time I have been using MM.
It always worked pretty well for me without any problems. Until I noticed today (or maybe a few days back) that there were no more events displayed in the mirror. I did have some power failures recently, but I think this isn’t the problem because the Holidays calendar is working fine

I have 2 personal calendars displayed, but both of them state “no upcoming events” while there are plenty of events to be displayed. The holidays calender I just added, is just for testing purposes, this works fine
Is there anything like a update i missed? I get my personal calender from a kerio server.
When I paste the .ics in my browser, I can download the file and view some contents.
I already tried to change https for webcal with no result.

Also created a new user on the Kerio server, with 1 upcoming event in the future.
If I run that ics file trough a ics-checker I do get a error result:

Errors
Invalid TZID value or missing VTIMEZONE component ("Amsterdam, Belgrade, Berlin, Brussels, Budapest, Madrid, Paris, Prague, Stockholm") near line # 22

Invalid TZID value or missing VTIMEZONE component ("Amsterdam, Belgrade, Berlin, Brussels, Budapest, Madrid, Paris, Prague, Stockholm") near line # 22

Any help would be appreciated.

do you see any errors in the terminal window where u started MM, or the pm2 logs if you use pm2?

I searched on that error and see entries from 2011/2013 timeframe, so altho MM uses an older calendar parser, this should be supported.

I think the problem was somewhere in my mailserver.
After a reboot all the appointments magicly reappeared.

Thank you for responding.
