#2

to change:

…top of the app-form

Ftitzbox is 7490

to add from outside using dyndns

#3

addendum:

when trying to connect via ios-app, using dyndns-adress and going over LTE
there is no entry written to /var/log/apache2/access.log.
Seems to be apache2 is’nt invoked

the /var/www/html/nextcloud/config/config.php is

<?php $CONFIG = array ( 'instanceid' => '---------------------', 'passwordsalt' => '------------------------', 'secret' => '-----------------------------', 'trusted_domains' => array ( 0 => 'local_address_of_server', 1 => 'localhost', 2 => 'dyndns-name_of_server', ), 'datadirectory' => '/mnt/r1p1/nextcloud', 'dbtype' => 'mysql', 'version' => '16.0.4.1', 'overwrite.cli.url' => 'https://dyndns-address_of_server', 'dbname' => 'nextcloud', 'dbhost' => 'localhost', 'dbport' => '', 'dbtableprefix' => 'oc_', 'dbuser' => 'the_user', 'dbpassword' => 'the_users_pw', 'installed' => true, 'maintenance' => false, 'forcessl' => true, 'overwriteprotocol' => 'https', ); Please excuse that I give the information in slices.
#4

That’s impossible, because CalDAV/CardDAV are based on the http protocol which is in the responsibility of the web server. I’m using https to connect to my server, what you should do too, and therefore the log file is e.g. named access_log.ssl.

#5

@kmichna Are you able to load the HTTPS page from any device at all outside your network? Try using the IP address instead of DDNS. You should be able to access it, although you may get an error about an untrusted name, and this is fine.

If you don’t get any entry at all in the Apache access log, then most likely the connection is never reaching your server. If your DDNS shows the correct public IP, then in all likelihood the problem is in your router.
