I used https://mybaseurl/remote.php/caldav as url during my first DAVdroid installation. Everything works fine.
Today, in order to get an A+ for the security check, I amend the DocumentRoot path by removing the “nextcloud” portion. Obviously, DAVdroid can sync no more then. Stupid me forget the original url used (above mentioned) and it took me some time to figure out it back. During the process, I find from https://www.davdroid.com/manual/accounts/ that the recommended way is to use root URL (/) with well-known URLs being configured.
I google a bit and it seems to me that (dot)well-known is from nginx that I have zero experience with. It also co-exist quite frequently with Letsencrypt. Do you gentlemen have any basic guide or good tutorial that I can follow and learn what (dot)well-known is, how it works, particularly under lighttpd?
p.s. the whole setup is for OpenTasks, so I put this thread here.
