Reverse Proxy for Secure Internet Access
By default, you can access the Dash app from http://localhost:8050. To be able to access from internet with https, use Synology reverse proxy.
See https://isolo.org/dokuwiki/knowledge_base/home_it/synology/matomo?s[]=reverse&s[]=proxy#create_reverse_proxy_for_https_access for creating reverse proxy.
