I installed Nginx-Proxy-Manager and MariaDB via "App templates" through Portainer on my Synology NAS.
When I visit the NPM login-page with port 81 and type in the first required login data admin@example.com with password changeme and push the sign in button nothing happens. What is the matter here?
I solved it myself with the help of this instruction https://www.wundertech.net/nginx-proxy-manager-synology-nas-setup-instructions/ : created a new container and configured it with the specs from wundertech.
