Nextcloud version (eg, 12.0.2) : NextCloud 22.214.171.124
Operating system and version (eg, Ubuntu 17.04) : Centos7
Apache or nginx version (eg, Apache 2.4.25) : Apache/2.4.6 (CentOS)
PHP version (eg, 7.1) : 7.2.10
I have mounted a Nextcloud 16.0.4 with an Onlyoffice and internally in the company it works correctly, the problem comes when I try to open a document from Nextcloud (docx, xlsx, etc …) from outside the business network the following error message comes out “The ONLYOFFICE cannot be accessed. Please contact admin” and it does not load the file, I repeat from within the company it works correctly. The question is to have the ONLYOFFICE url published on the internet so that files can be edited from outside the company network or once connected from outside to the Nextcloud, this is the one who manages the connection internally with the ONLYOFFICE server.
