Need advice to setup HaRP with official Docker Container nextcloud:stable-apache

[W11T]

Using the official Docker-Container nextcloud:stable-apache i am unable to setup the new AppAPI.
The Container appapi-harp starts as well as the test-app nc_app_test-deploy.
But the heartbeats get lost on their way back.

In Nextcloud-Log:
[app_api] Warnung: Failed heartbeat on http://nextcloud/exapps/test-deploy for 10 times. Most recent status=0, error: Client error: GET http://nextcloud/exapps/test-deploy/heartbeat resulted in a 400 Bad Request response:In Apache

lots of messages in access.log:
“GET /exapps/test-deploy/heartbeat HTTP/1.1” 400 14013 “-” “Nextcloud Server Crawler”

HaRP logs:
[DEBUG] [0e35e26b] Received hello handshake, responding with agent capabilities of: ''
[DEBUG] [0e35e26b] Health check, immediately disconnecting

I found this issue #44 suggesting to extent the apache VirtualHost configuration.
But modules proxy_module and proxy_http_module are not available in this Nextcloud/Apache/PHP-Container.

Please advise.

Hello. Can you ask the maintainers of that image to add such modules?
You can link them to this issue, without adjusting VirtualHost HaRP will not work.
