@enr00ted Maybe other apps use other CalDAV methods (for instance, only PROPFIND instead of the better-suited REPORT calendar-query). If these clients are open-source, you can have a look at the source code – would be interesting.
DAVx5 with Synology
I have a SYNOLOGY DS218 play.
DAVx5 worked very well when I was under LineageOS 15.1, i.e. Android 8.1.
Since my time on LineageOS 16, Android 9, I have been having problems.
I have 2 accounts to synchronize. When I set up my A account, I only have access to CardDav and no more CalDav. I can no longer also synchronize my B account.
Strangely, when I reset DAVx5, I can configure my account B but no longer my account A. And I still don’t have access to my calendar. However, I followed the instructions here https://www.davx5.com/tested-with/synology/.
I get a message when I try to configure my 2nd account “No access possible CaldDAV or CardDAV.”
Here is the detailed message davx5-info.txt
If you have any ideas, I’m a buyer
I see you used https://192.168.0.46:8443/addressbooks/users/violainegeorges/addressbook as URL
Maybe try without the appended “addressbook”. This should only be used for pretty old servers. But I think your DMS should have gotten updates.
Also there is an “unauthorized exception”. So the connection is working but you’re not allowed to access it with the given credentials.
Maybe this information helps…
Thank you for your answer.
In the meantime, I have reset my SYNOLOGY and it works
What I don’t understand is that the CalDAV and CardDAV packages were up to date and synchronized with another phone with the format http(s)://example.com:port/addressbooks/users/YOUR_USERNAME/addressbook.
In short, the important thing is that it works.
Have a good day.
