When I restarted the server, Collabora can’t connect to the documents.
There was no problem before restarting.
When I click the document, the screen switches to Collabora. “Connecting …” is displayed for several minutes. Then a dialogue "Well, this is embarrassing, we can not connect to your document."
After that, I tried again to restart the server, but it is exactly the same again.
I deleted the Collabora container and reinstalled it. This also doesn’t improve.
Nextcloud doesn’t recognize this as an error and there is no state record in the log.
It is not an existing file, it is the same for a newly created file.
How do I become able to use Collabora?
CentOS 7.3, nginx 1.11.13, PHP 7.1.7
