So your previous config might have looked like:
###### CARDDAV
upstream syno_carddav {
# The keepalive parameter sets the maximum number of idle keepalive connections
# to upstream servers that are preserved in the cache of each worker process. When
# this number is exceeded, the least recently used connections are closed.
keepalive 50;
server w.x.y.z:5008;
}
The newer DSM-7.0 has the calDAV endpoint
https://w.x.y.z:5001/.well-known/carddav
However this is not the full story
the
/.well-known
will redirect to/carddav/.web
When you call it in the Webinterface you will see :
Radicale works!
