I just installed Nextcloud 15.0.4.on a completely fresh Ubuntu 18.04 server. I created a few groups and users and then installed and activated Collabra. Although it allows me to create new documents, I can not open them. When I try, I get the message
Failed to load Collabora Online - please try again later
I don’t have the foggiest idea how to approach this problem and appreciate some help. I am happy to provide any information necessary, if I know what’s needed.
Thanks in advance.
