Connect OHIF to Orthanc using Docker containers on Synology nas

Hi,
I need to connect OHIF Viewer to Orthanc.
As a physical server I use a Synology nas with the DSM 7.1 operating system version.

I currently use Orthanc and OHIF as docker containers.

Orthanc: Version: mainline (20220510T030919)
name jodogne/orthanc-plugins/

OHIF: Version 4.12.35
name ohif/viewer/

Synology’s ip address is 192.168.2.167
The ports of the containers installed on the Synology nas are mapped as follows:
Orthanc container - Synology
4242 > 49178
8042 > 49179

OHIF container - Synology
443 > 49182
80 > 49183

Both applications called individually work correctly.
If I try to connect OHIF to Orthanc, using the port 49183
I don’t see the my Orthanc series but those of the OHIF demo website.

I have read many posts on the subject, and I think I understand that my problem is with the configuration of nginx. Unfortunately I don’t know it and I can’t figure out how to configure it.
Can anyone help me ?
A thousand thanks ….

Daniele.

These are the configuration files I use:
