Ah, I forgot to set my domain in lemmy.hjson. Thank you for the tip! And I will consider !selfhosted@lemmy.world if I encounter any problems in future, thank you :)

I’m hosting syncthing on my server to sync obsidian notes between my pc and phone, even when one of the devices is offline. I find it very useful. Also, nextcloud, jellyfin, qbittorrent, monero node and netdata for monitoring my server
