Calendar subscribed from link not displayed


I am trying to move my nextcloud from one server to another.

In the old one, I am using nextcloud 21.0.0 with a LAMP set up. On the new one ( 28.0.1), I use docker-compose with traefik as reverse proxy.

Everything is working well except when I try to add a Calendar from an ics link (it’a a Google one). In the new one, it adds the calendar but not events are displayed. It works with my old server and also on Android with ICSx5.

There is no errors in the logs.

Do you have any clue?
