Installed Grafana, then lost access to server

Hi there, i’m a abit of a newbie to Linux, had seen a Reddit post about Grafana and wanted to set it up myself. So i did. Only now i cannot access my Nextcloud, pi-hole dashboard, or anything else using my IP. Grafana on the other hand works perfectly :slight_smile:
I did set the port to 3000, so thought that would prevent it from ruining other instances…
Oh, i also lost “access” to my server via ssh… The server is hosted from home, so I have physical access to it.
Where did i go wrong and how can i avoid/correct my issue? Any help is appreciated.
