I am building my own caldav server and I am trying to get it work with DAVDroid. I am running a DAVDroid client on my android phone(Android 7). I could make a account on DD and syncronizing my calendar goes without any errors. In fact the phone's calendar gets not syncronizer. I have noticed from my servers logs that DD client is making one PROPFIND when making "Refresh calendar list". It is making no queries when running common syncronization from DD or from phone's calendar app.
Here I have a DAVDroid log:
Could anyone tell what is wrong with my server?
Why client is not making any REPORT query?
There is a KeyStore exception. What does that mean?
