Unable to sync with Synology Cardav

[Aurel P]

Hello,

I installed davx5 on my new realme X2 pro by building source with Android Studio.
I’m connected to my Cardav server, but when I start à sync, I have a error message :

HTTP server error - HTTP 500 Internal server error.

My davx5 log file
davx5.txt

Thanks in advance for you advices.

Hi,

It’s a server error. Please check your server.

Did you import the contacts directly from Android vcf (vCard 2.x) to Synology?

@Aurel-P This is always occuring when you import erroneus vcf directly into the Synology. Synology does not correct these vcfs and on DAVx5’s request the server crashes by delivering these data.

• Please delete the address book.
• Create an empty one and make a DAVx5 account connected to this new address book.
• Then import the vcf files directly on Android into this new account.
• Synchronize
• Then it should work.
