Unable to connect to host from dev.container with Rancher Desktop

[PureKrome]

Hi folks,

I'm trying to connect to my host machine from inside my dev.container - which I assume is just a docker instance running a specific image ... powered by Rancher Desktop.

I just can't access anything in my host.

for example:

curl -v "http://host.docker.internal:5000/api/profile"
*   Trying 172.17.0.1:5000...
* connect to 172.17.0.1 port 5000 failed: Connection refused
* Failed to connect to host.docker.internal port 5000 after 1 ms: Couldn't connect to server
* Closing connection 0
curl: (7) Failed to connect to host.docker.internal port 5000 after 1 ms: Couldn't connect to server

From the host machine (win11) i can see i'm binding to all:

 Get-NetTCPConnection -LocalPort 5000 | Format-Table LocalAddress, LocalPort, State

LocalAddress LocalPort  State
------------ ---------  -----
0.0.0.0           5000 Listen

Can this be done with dev.containers + Rancher Desktop?

I don't have k8's installed because I thought that was going to be an overkill, here?

EDIT: OH! i forgot to say i also modded the firewall based off the docs here:

New-NetFirewallRule -DisplayName "WSL" -Direction Inbound -InterfaceAlias "vEthernet (WSL (Hyper-V firewall))" -Action Allow
