So, basically, the trick to setting this up in Caddy is more one of not doing anything. Caddy is so much smarter than Nginx that it just figures out all this stuff for you.
So this:
# Notes Server - With WebSocket
server {
listen 80;
server_name notes.domain.com;
return 301 https://$host$request_uri;
}
server {
listen 443 ssl;
server_name notes.domain.com;
ssl_certificate /etc/letsencrypt/live/notes.domain.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/notes.domain.com/privkey.pem;
include /etc/letsencrypt/options-ssl-nginx.conf;
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem;
location / {
proxy_pass http://localhost:5264/;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $host;
proxy_read_timeout 3600;
proxy_send_timeout 3600;
}
}
in Caddy becomes this:
auth.domain.com {
reverse_proxy IP_ADDRESS:8264
}
Yeah. This is why I love Caddy.
In the end I only had to include a couple of the header modifiers to get everything working. So my finished file looked like this:
auth.domain.com {
reverse_proxy IP_ADDRESS:8264 {
header_up Host $host
header_up X-Real-IP $remote_addr
}
}
notes.domain.com {
reverse_proxy IP_ADDRESS:5264
}
events.domain.com {
reverse_proxy IP_ADDRESS:7264
}
mono.domain.com {
reverse_proxy IP_ADDRESS:6264
header / Cache-Control "public, no-transform"
header / X-Cache-Status $upstream_cache_status
}
Obviously, update “domain.com” and “IP_ADDRESS” to the appropriate values. I’m actually not even 100% sure that all of that is necessary, but my setup seems to be working, including the monograph server.
One very important aside though; in your .env file, don’t do this:
AUTH_SERVER_PUBLIC_URL=https://auth.domain.com/
NOTESNOOK_APP_PUBLIC_URL=https://notes.domain.com/
MONOGRAPH_PUBLIC_URL=https://mono.domain.com/
ATTACHMENTS_SERVER_PUBLIC_URL=https://files.domain.com/
Those trailing slashes will mess everything up. Strip them off so it looks like this:
AUTH_SERVER_PUBLIC_URL=https://auth.domain.com
NOTESNOOK_APP_PUBLIC_URL=https://notes.domain.com
MONOGRAPH_PUBLIC_URL=https://mono.domain.com
ATTACHMENTS_SERVER_PUBLIC_URL=https://files.domain.com
Took me a while to work that one out.
I might still need to tweak some of this. I’m getting an occasional “Unknown network error” in the app, but all my notes are syncing, monographs publish just fine, and generally everything else seems to work, so I’m not entirely sure what the issue is that Notesnook is trying to tell me about, or if it’s even something I need to fix.
Edit: OK, the issue was that I didn’t have files.domain.com setup. Just directly proxying it solves one error, but creates another, so I’ll need to play with that part a little more. It’s probably down to Minio doing it’s own proxying on the backend (because it rewrites http requests at 9009 to https at 9090). Will update when I get it working. Anyway, for now everything except attachments seem to work.
I just use a DDNS updater. That’s honestly good enough for most purposes.
Alternatively, you could use a service like Zerotier, Tailscale or Netbird to create a virtual private LAN connection to a free Oracle VPS, then route the traffic from the VPN to your home network.
