The above was my default calendar. If I use another one, the URL is:
[...]/horde4/kronolith/data.php?actionID=export&all_events=1&exportID=101&exportCal=internal_900853ea74a7a2bdfb3027b63dd7cf45#week

but it does not work either.

for the default calendar, the 
"Subscription URL — Subscribe from another calendar program" 
is

[...]/horde4/rpc.php/kronolith/mk/mk.ics

and for the other one:
[...]/horde4/rpc.php/kronolith/mk/900853ea74a7a2bdfb3027b63dd7cf45.ics

no entries in the horde log on the "INFO" level.

but in the webserver error log, I get

 [error] [client 134.99.82.26] client denied by server configuration: /srv/www/htdocs/kronolith

horde is installed in /home/horde4, so this is definitely wrong. 
Or: it is correct, that the server denies access, but it is wrong that
this URL is being used.

Does the above URL mean that horde is trying so access
www.example.com/kronolith instead of www.example.com/horde4/kronolith ?

apache configuration is:

Alias /horde4 "/home/horde4/"
<Directory /home/horde4/>
  Options Indexes FollowSymLinks ExecCGI
  AllowOverride None
  order deny,allow
  allow from all
</Directory>
