CalDAV Synology not working

[MyNameIsOka]

Hi everybody,

I am trying to setup CalDAV to Synology and I just can't get it to work.
I already set it up on Android via Tasks.org and it seems to work properly.

However, on Super Productivity I always get an 401 error.
I can see in the console, that Super Productivity tries to use a my-sync-file.json file but I am not sure if that is really present in Synology.

Did somebody successfully setup a sync between Super Productivity and Synology?

Can't help you with the details, but a 401 indicates that there is something wrong with the authentication. You can also use the Network tab to debug this further which you can open by pressing Ctrl+Shift+i. Good Luck!

Thank you for your reponse!
In the Network tab it seems that the URL is changed.
The URL from Synology Calendar is https://URL:PORT_NUMBER/caldav/USERNAME
But the call is changed to https://URL:PORT_NUMBER/caldav.php/USERNAME/my-sync-file.json
Could that be the reason?
