Hi @Joerg0100

The log mentions { [Error: SSLHandshakeException] code: undefined }, which may point to your TLS setup. Are you using a self-signed certificate?

Hi Marcel,

no, I'm not using self-signed certificate on my Huawei Mate20.
In the meantime, I noticed that the synchronisation sometimes worked after I went to a certain https page in Firefox for android. But that no longer works either.
Could it have something to do with the certificate of the webdav provider freenet.de? Unfortunately, I have no more ideas.

TLS in Android is very voodoo like I get the feeling :( I'm also out of ideas

Hi, I get the same error but with a self-signed certificate. Is there any solution for self-signed certificates?

Edit: Problem solved by installing the self-signed certificate to androids ca-certificates on the smartphone.

Can you please share how you installed the self-signed certificate to androids ca-certificates on the smartphone.
I couldnt find any useful guide, so I downloaded cert from nginx proxy manager and tried to install it on android. Seems fine but it doesnt work
