I'm reconfiguring DavDroid to sync with my ownCloud 9.1 Server. I have a SSL-Certificate issued by CA Cert. It also shows correctly if I open the https server URL in the phones browser. But when I setup my server in DAVdroid, I get a random untrusted certificate showing up. I'm shocked and concerned about the saftey with DAVdroid. I uninstalled DAVdroid and reinstalled the latest version from F-Droid. Same problem.
Please let me know where this certificate comes from.
This is my certificate...
