Configure OnlyOffice Document Server to use HTTPS:

Stop NGINX service:

sudo service nginx stop

Create /etc/nginx/ssl directory to store certificates and keys:

mkdir /etc/nginx/ssl

Obtain the necessary certificates and keys from a 3rd party trusted Certificate Authority before going further

Place 3rd party certificate and key in /etc/nginx/ssl directory as below:

/etc/nginx/ssl/office.pem

/etc/nginx/ssl/office.key

Backup existing ds.conf file:

cp /etc/onlyoffice/documentserver/nginx/ds.conf /etc/onlyoffice/documentserver/nginx/ds.conf.BACKUP

Copy ds-ssl.conf.tmpl to ds.conf:

cp /etc/onlyoffice/documentserver/nginx/ds-ssl.conf.tmpl /etc/onlyoffice/documentserver/nginx/ds.conf

Edit new ds.conf file and replace all parameters with double curly brackets {{ }} for the actual values:

vi /etc/onlyoffice/documentserver/nginx/ds.conf

ssl_certificate {{SSL_CERTIFICATE_PATH}};
ssl_certificate_key {{SSL_KEY_PATH}};

So it looks like below:

ssl_certificate /etc/nginx/ssl/office.pem;
ssl_certificate_key /etc/nginx/ssl/office.key;

Additionally, edit the ssl_protocols line and remove all but TLSv1.2 entries so it looks like below:

ssl_protocols       TLSv1.2;

Start NGINX service:

sudo service nginx start
