i’ve just installed USC with Nextcloud and OnlyOffice Docs (both to the last versions).
Onlyoffice is up and running, if a go to https:///onlyoffice-documentserver i got the window.
Nextcloud is also up and running.
The problem is that if i would like to open a document from Nextcloud with OnlyOffice, i got the error message:
ONLYOFFICE cannot be reached. Please contact admin
Any suggestion how to fix it?
