Hi there, I was intrigued by the idea of self-hosting my social media accounts, but was more or less a complete noob with all things hosting. However, with the help of the community here (and quite a few hours spent on it) I finally have a working setup! Mastodon, Matrix, Lemmy, Nextcloud all self-hosted behind Nginx Proxy Manager.
Google can find a lot of answers, but sometimes some really specific input is needed - which you guys have provided over the last couple of weeks - so I just wanna say thank you for that!
I have fail2ban running as well, didn‘t mention it in the op. Also closed all ports beside 80 and 443, which are routed through my NPM proxy. SSH is allowed, but login only with ssh key, no pw authentication.
So far it‘s running well, but I expect things to break when I‘ll need to update parts of it. I have a snapshot from which i can reinstall, but recurring backups need yet to be set up.
