iCal calendar problems

Hi,

I am currently facing two issues with the iCal Calendar:
1. After moving the site from my stage to production, the calendar does not show any results using the iCal URL
2. The iCal calendar showed the wrong event times (seems like timezone related)

The WordPress timezone is set to “Berlin”:

The Sportspress timezone is set to “Berlin”:

Here is my next upcoming event (23.04.2022 15:00 / 3pm)
https://www.wiesbaden-phantoms.de/event/wiesbaden-phantoms-vs-saarland-hurricanes/

This is what the event looks like in WordPress:
– https://prnt.sc/TxY4OSaNwhWS

This is what the calendar looks like in WordPress (I don’t understand why all dates are shown as “27. September 2021” btw.):

Problem number 1 – No Events added to the Google calendar at all (Production site):
https://www.google.com/calendar/render?cid=webcal%3A%2F%2Fwww.wiesbaden-phantoms.de%2Fcalendar%2Fkalender%3Ffeed%3Dsp-ical

Problem number 2 – Events showing the wrong times:
https://www.google.com/calendar/render?cid=webcal%3A%2F%2Fredesign.wiesbaden-phantoms.de%2Fcalendar%2Fkalender%3Ffeed%3Dsp-ical

Help is very welcome ??

Best regards,
Sebastian
