Hi,penzoiders, i've just install onlyoffice document server, but after reboot , i can't access to onlyoffice document server.
and when i excecute latest line for SSL , after complete . nginx can not starting :

cat: /etc/onlyoffice/documentserver/nginx/onlyoffice-documentserver-ssl.conf.template: No such file or directory
Job for nginx.service failed because the control process exited with error code. See "systemctl status nginx.service" and "journalctl -xe" for details.
