nextcloud + collabora + pi4 32bit + server demo

i setup and up nextcloud + collabora client. set collabora for to use with a demo server and all look ok but when i try to open a document i got this error:

failed to readd document from storage…

i set https access following guide in forum with dietpi-letsencrypt

open 443 and 80 ports on router


many thanks for your message. Did you installed collabora server as well?

no, i set it with demo server.

tested with docker nextcloud+collabora container and work well.
