Can you give some information about your server setup?

Debian 12 VM inside proxmox Docker with docker compose with few other programs Wireguard VPN to the remote vps Caddy proxy tunneling traffic thru wireguard to local server from VPS that has public IP and domain name.

I'm not sure what else to mention, if you want me to elaborate on something or have other questions - feel free to ask
