I get this as a message in my Nextcloud when I try to read a PDF (having activated the application that is fine) :
PDF.js v1.9.426 (build ID: 2558a58d)
Message: Unexpected server response (0) while retrieving PDF “https://cloud.mydomain.com/remote.php/webdav/Nextcloud%20Manual.pdf”.
Same message with another PDF of course… that I can read on PC (by downloading it).
Is it a Nextcloud problem, or a server problem as the message says ? Hosting: Infomaniak
