What server do you use?

Please provide all steps to reproduce.

You’ve only pasted the debug info, which is no error log.

Sorry. I clicked Submit but I was still collecting more infos.

The carddav server is generated by EasyRedmine software v.2016.07.03

I was able to connect and find cardav addresslist but at the first sync i get a sync error with that debug infos attacched.

I used CardDav Sync free and worked fine downloading contacts (some errors uploading new ones) but was looking to move away due to lack of support.

Can I give you any other info?

[devvv4ever]

Most likely this is is a server bug… Can you provide a test account? Then we can have a closer look at it.

[lrealdon]

I sent you credentials by chat.
Thank you so much.

[rfc2822]

Hello,

I was able to reproduce the problem. As soon as DAVdroid tries to download the contacts with REPORT addressbook-multiget, the server returns “500 Internal Server Error”.

addressbook-multiget is mandatory for CardDAV servers and required for fast contact synchronization.

Can you please report this problem to the server vendor and provide some reference (for instance, a link to the bug report) here?
