Cannot ssh into service running through openwrt

I have a proxmox server that houses a few containers. Some of these containers are running through openwrt which has a vpn enabled. One of these containers is my Homepage LXC. When i try to ssh -p 3000 192.x.x.x i get.

key_exchange_identification: Connection closed by remote host
Connection closed by 192.x.x.x port 3000.

Further, from my proxmox host when I try to SSH into my OpenWrt LXC container I get connection refused. Any help would be great, I purely want to SSH into my homepage LXC becuase configuring css files and what not is much easier in visual studio.

Wireguard is your friend

Do explain please sir.

have you cleared out your old keys?

In linux - rm ./ssh/known_hosts...
