I’m using owncloud client on Ubuntu 16.04 to sync with Nextcloud server 10.0.
I’m able to properly configure the account and successfully sync data with the server.
But when I attempt to login for the second time, I have the “No Connection to owncloud” error.
I tried a lot of things, using Ubuntu 16.04 official repository installation and owncloud Suse repository for Ubuntu 16.04.
Both client (./Nextcloud/.owncloudsync.log) and server (/var/nextcloud/data/nextcloud.log) logs didn’t show errors.
Nextcloud server is configured to accept SSL self-signed certificate:
'check_for_working_webdav' => false,
The HSTS is configured:
<IfModule mod_headers.c> Header always set Strict-Transport-Security "max-age=15768000; includeSubDomains; preload" </IfModule>
What could be the problem?
Maybe a time-out error? (first login require a lot of seconds)
