EDIT - found the issue, it was a TLS setting.
I am able to make the tunnel work with any device on my native lan, but not devices on my vlan. Am I doing something wrong? I will give an example below.
Native Lan - 192.168.2.1
VLan - 192.168.80.1
Public Hostname
reolink.mydomain.com → http://192.168.2.242 - works great
proxmox.mydomain.com → https://192.168.80.201:8006 - will not work
