I just installed the add on Nextcloud for filelink. I run a Nextcloud instance on my Raspberry Pi with a Letsencrypt certificate. This works fine with the sync client and the web ui. Syncing the calendar and the contacts with Thunderbird and Cardbook works fine, too.
The add-on creates the directory /Mail-attachments, so login works and credentials are correct. But it shows: Used memory: 16,0 GB, free memory: 0 Byte.
When I write a mail with attachment, the upload works. The file is stored in /Mail-attachments. The add-on shows an error:
“Beim Datenaustausch mit myserver.com trat ein unbekannter Fehler auf.”
(“An unknown error occurred when communicating with myserver.com.”)
Thunderbird creates no link and sends the Mail with attachment.
How can I find the error?
Edit: In the developer tools I found:
“2017-10-08 23:20:15 Nextcloud ERROR Could not retrieve password”
Hm, but the upload works?
(Edit: english error added.)
