@rfc2822 thank you very much!

In DAVx⁵ 2.6, there will be a warning when there’s no validated Internet connection. So when you see this, you will know there’s something wrong with the connection:

Thanks for the confirmation and the translation!

@Louis non-admins can’t, but I did it now

Thanks for the update! Good to know that SRV records are working with Synology, too (as they should).

@Fraggle Thanks for the update!

@NIPE-SYSTEMS Thanks for the update!

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.

@maction Thanks for the confirmation!

@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!
