This doesn’t help with your current issue, but you should use Nextcloud All-In-One instead of setting up individual containers like in the tutorials you linked. It will create and manage all the containers that are needed.
Domains are pretty cheap, so you may want to consider whether not using one is really worth the effort.
The article sounds like you could have the A records on a local DNS service like Unbound or Pi-hole instead of public DNS. I guess maybe they just need to be defined somewhere that they’ll resolve for your Caddy instance.
Keepass has a synchronization mechanism, maybe you can get it to work between your phone and your PC?
If the files to be synchronized are accessible via a protocol that KeePass supports by default (e.g. files on a local hard disk or a network share, FTP, HTTP, HTTPS, WebDAV, …, see the page ‘Loading/Saving From/To URL’ for details), then no plugins/extensions are required.
If one of the files to be synchronized should be accessed via SCP, SFTP or FTPS, you need the IOProtocolExt plugin, which adds support for these protocols to KeePass.
If one of the files to be synchronized is stored in a cloud storage: for most cloud storages, there is an integration with the local file system available (i.e. you can access your stored files using Windows Explorer). For example, Dropbox, Microsoft OneDrive and Google Drive provide such an integration. If such an integration is available, it is recommended that you access your database file this way; this often works better than accessing it via a protocol like FTP or WebDAV. If no such integration is available and your cloud storage also is not accessible via a standard protocol, a specialized KeePass plugin for this cloud storage might be available.
Like the other commenter said, you can use Let’s Encrypt without needing to expose anything on your network to the internet. I set it up on my network a couple of weeks ago using this guide; I couldn’t get caddy to work with duckdns but it worked with Cloudflare without any trouble.
PalWorld being number 2 is pretty impressive considering it only came out on the 19th. I suppose the huge number of players would make up for the relatively limited time.
Have you tried DIGImend kernel drivers? That seems to have some support for the tablet, although there’s an open issue around it. It supports installing from source so it might be more flexible than the installer for the official drivers.
It’s “many” like in “Many people on twitter are saying…” i.e. they found 3 or 4 people saying crazy shit and acted like it was a big thing.
