On checking calendar syncs today I found that all of a sudden syncs are hanging / waiting. Up until a couple of hours all seems was fine. See the screenshot. https://share.cleanshot.com/Z1jw7936
I have another site and there all works fine so I assume that this is not a hosting/server issue.
I have checked the ical links on an external calendar and they import fine
Any idea what could be the reason for this suddenly stopping?
Ok, no idea why this was happening. Logs are set to auto delete every day. I however manually deleted the logs today and after that synced calendars manually by clicking “sync calendars”. It then worked immediately and keeps syncing as scheduled till now.
