Proxmox 6.3 API via IPSec VPN not working

[BeDazzler]

Hi,

I have a new Proxmox 6.3 server installed with remote access via IPSec VPN (we use pfSense at both ends of the VPN).

On the local network next to the Promox server everything works fine and I can access both web interface and API with no issues.

However, when remote at the other end of the IPSec VPN, whenever I try to access the Proxmox API it gives me Empty Server Reply errors.

A simple curl call to the server via it's IP or SSL name on 8006 provides the following error:
> GET /api2/json HTTP/1.1
> Host: xxxxxx:8006
> User-Agent: curl/7.77.0
> Accept: */*
>
* Empty reply from server
* Closing connection 0
curl: (52) Empty reply from server

Is there something I need to do or configure on the IPSec VPN for this to work remotely ?

ICMP and SSH work fine.

Thank you.

A simple curl call to the server via it's IP or SSL name on 8006 provides the following error:

do you connect to https://ip.addr.of.pve:8006?
(the empty reply happens if you connect to http instead of https)

Hi Stoiko,

Yes, all connections are on HTTPS/SSL.
The certificate is valid and working.

Normal admin works fine using the SSL hostname.
The curl command output does show it found the SSL.

Thanks
