cannot connect to Postgres Pro database in Azure Container

**Describe the bug**
I have the following yaml-file to create Azure Container:

name: debiandocker
apiVersion: 2019-12-01
location: northeurope
tags: {}
properties:
containers:
- name: debiandocker
properties:
image: XXX/pgpro-ent13-debian-x64:13.41.20211031
ports:
- protocol: tcp
port: 5533
environmentVariables:
- name: PGPRO_SUPERUSER_PASSWORD
value: azure
- name: PGPRO_PORT
value: 5533
resources:
requests:
memoryInGB: 1
cpu: 1
imageRegistryCredentials:
- server: XXX
username: YYY
password: ZZZ
ipAddress:
ports:
- protocol: tcp
port: 5533
type: Public
osType: Linux

If I specify the same value for both 'port:' and 'PGPRO_PORT' (say '5533 as in example above) I can create Azure Container and can connect to Postgres Pro database via 'psql' in Azure Container outside of it:

root@ubuntu20:~/docker# psql --dbname=postgres --username=postgres --host=$fqdn_id --port=5533 -c "select pgpro_version()"
Password for user postgres:

But if I use different value for 'port:' and 'PGPRO_PORT' (see example below) I can create Azure Container and cannot connect to Postgres Pro database vias 'psql' in Azure Container outside of it:

root@ubuntu20:~/docker# psql --dbname=postgres --username=postgres --host=$fqdn_id --port=5534 -c "select pgpro_version()"
psql: error: server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.

name: debiandocker
apiVersion: 2019-12-01
location: northeurope
tags: {}
properties:
containers:
- name: debiandocker
properties:
image: XXX/pgpro-ent13-debian-x64:13.41.20211031
ports:
- protocol: tcp
port: 5534
environmentVariables:
- name: PGPRO_SUPERUSER_PASSWORD
value: azure
- name: PGPRO_PORT
value: 5533
resources:
requests:
memoryInGB: 1
cpu: 1
imageRegistryCredentials:
- server: XXX
username: YYY
password: ZZZ
ipAddress:
ports:
- protocol: tcp
port: 5534
type: Public
osType: Linux

In the latter case I can connect to Azure Container via

az container exec \
--resource-group ABC \
--name debiandocker \
--exec-command "/bin/bash" \
--container-name debiandocker

and make sure Postgres Pro database is up and running and it listens on the specified 5533 tcp-port, I can connect to Postgres Pro database via 'psql' only inside of Azure Container.

**To Reproduce**
see above

**Expected behavior**
to be able to use different values for 'port:' and 'PGPRO_PORT', i.e. for external and internal ports

**Environment summary**
root@ubuntu20:~/docker# az version
Azure-cli Azure-cli-core Azure-cli-telemetry
----------- ---------------- ---------------------
2.29.2 2.29.2 1.0.6
root@ubuntu20:~/docker# az --version
azure-cli 2.29.2
core 2.29.2
telemetry 1.0.6

**Additional context**
No issue with native docker container (native docker-compose)
