Multiple Orthanc servers + HAProxy

Hello!

I have installed HAProxy as a load balancer in front of two Orthanc servers.
HAProxy has an IP address of 192.168.0.1
Orthanc server 1 has an IP address 192.168.0.2 port 4242 AETitle = PACSORTHANC
Orthanc server 2 has an IP address 192.168.0.3 port 4242 AETitle = PACSORTHANC

At the doctor’s workplace, a third-party pacs is used, in which it is necessary to receive data from my cluster.
On this server I wrote the following settings
IP = 192.168.0.1
Port 4242
AE title PACSORTHANC

The C-Store method from the third-party pacs and other devices in the direction of our cluster work correctly.

We have a problem with the C-FIND method, when accessing a third-party pacs from any of our servers. (because the request to a third-party pacs server comes from the address of one of the our servers, but the address of the load balancer is registered on the third-party pacs, so it cannot give the data)

Are there any recommendations on how to properly configure a cluster of two servers and a load balancer HAProxy?

Maybe this documentation can help and show a light: Scalability of Orthanc — Orthanc Book documentation
