SSL handshake issue with Davx5

I am facing a SSL handshake issue from an android 4.4.2 device.

i have a setup where I sync my contancts on Nextcloud with multiple Android devices using Davx5 (davdroid). It used to work fine but now one of my devices stopped syncing. Don’t know for sure but I have a sense that this could be related to the snap update which affected a specific Android version because my other android device (and thunderbird as well) is continuing to sync properly.

The error I am getting from Davx5 says:

2019-04-16 10:35:50 2 [HttpClient] <-- HTTP FAILED: SSL handshake aborted: ssl=0x5e210c78: Failure in SSL library, usually a protocol error

error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure (external/openssl/ssl/s23_clnt.c:744 0x5e2b2830:0x00000000)

Full Error Log:

From what I read on Davx5 forums, this could be about incompatible ciphers ( But I am not sure what they are, how to test or change them in a nextcloud snap installation setting.

Any idea how to proceed with troubleshooting?

up. this is still a problem.

The problem is solved by davx5 update (2.5) in May.
