Thanks, actually I just tried to remove my account and create a new one on DavX5… and everything works well. It took be about 10mn. That’s great. Thank you for your concern!!

@acu Works here again, too. I’ll set this to solved.

@bingo Thanks for the update!

@Shun-Feng Interesting, I have never heard of this module. Thanks for the update!

@Dan-cer Thanks for the update! Good that it now works for you

Unfortunately, I dont know why some calendar apps have problems… maybe resetting them will help, too. Or just use another one

I’m happy that it know works for you and thanks for sharing the solution!

14 August 2019 Amazing! I received again the synchronization error. Solved again by de-selecting - again! - Carddav. And it is for exactly the same issue as before: (printscreen taken 2 hours ago): https://i.postimg.cc/X7T45Byk/Screenshot-20190814-105154-at-bitfire-davdroid-carddav.jpg I know that I did not touch the phone as it was linked by usb on my desktop (hence always fully charged), and I was away 3 days without it (and with no one accessing my place): it was simply store there, alone in the dark… There is something that triggers Carddav, but what ? … a mystery (edit : all updates are manual, never auto. However, I recall having authorized several manual updates: an Android system update about “WebView”, “Booking”, “Visorando”, “Meteo France” and “Firefox”)

Sorry for the delay: Works for me! Thanks a lot for helping!

Ok, happy that it now works for you

@rfc2822 Thanks. Yes, the new version solved the handshake issue.

Excellent We’d be very happy for a nice review in the Play Store. Would be cool! Thank you!

Seems you already have committed a fix to master (the email I got still talked about creating a branch). Will test that and report back.

Should be fixed with https://gitlab.com/bitfireAT/davx5-ose/commit/5709fd38d9df62ca0afc03e764487917fc9cc2e5 / 2.5.1, will send an APK for testing. For testing: Install the new APK Open DAVx⁵ and the account Switch to Webcal tab Swipe down to refresh the Webcal list Subscribing to webcal(s):// URLs should now work

@rfc2822 thanks again

Thanks for the update!

@synncgw I see, so the server previously sent Content-Encoding: gzip without actually using gzencode(), which caused the problems (no crash ). In my opinion, okhttp/okio should accept 0-octet gzip responses nevertheless, but the specific problem should be fixed with your changes, so I have marked the topic as solved.

@rfc2822 Afaik Nextcloud allows to store all kind of recurring events in the database, but lacks of a fully featured event editor. Currently I found these issue tickets related to the editing of recurring events: New concept for entering recurrence rules / full-featured recurrence settings special dialog when editing repeating events

Thanks for the explanation. I guess it was a problem with Baïkal after all. I have “fixed” it by switching to DAViCal. Very intimidating documentation & UI, but almost nothing needed to be configured and it Just Worked. So, DAViCal is the server DAVx5 syncs everything on Android on the desktop I use vdirsyncer & khal for the calendar only (vdirsyncer still refuses to sync my contacts), and SoGo connector for contacts on thunderbird. It’s been a long day.

@pescepalla Thank’s a lot! Your solution workes on my Xiaomi 5s plus with nextcloud on an own server in my LAN and using DAVx⁵ for synchronisation after I’ve searched two days where the problem comes from. By accident I installed nextcloud 15 and deleted and reconfigured DAVx⁵’s account. So I was not clear if it’s a nextcloud or a DAVx⁵ problem. Finally I found out in the nextcloud logs an entry webdav Sabre\DAV\Exception\NotAuthenticated: No public access to this resource., No 'Authorization: Basic' header found. Either the client didn't send one, or the server is misconfigured, No 'Authorization: Bearer' header found. Either the client didn't send one, or the server is mis-configured, No 'Authorization: Basic' header found. Either the client didn't send one, or the server is misconfigured Still misleading, I checked everything related with passwords and accounts. Android doesn’t sync if it can’t connect to a working captive_portal_https_url, even if you choosed in the internet access settings for your network not to ask the question anymore and the internet works as far, as possible in China. And that with LineageOs. As many people not only using their own local nextcloud installation inside a LAN that is kind of a strange setting with Android in China at least. Thanks again, @pescepalla !
