Homepage (docker) behind squid proxy

[maxsmooth]

Description

Hello everyone.
In my company we installed Homepage in a docker container, we use squid proxy to go out on internet.
Widgets for local services work well, but not those that retrieve data from the internet such as healtchecks.io which returns the error "ENETUNREACH".
I have already set the HTTP_PROXY and HTTPS_PROXY environment variables, if I enter in the shell with the command
docker exec -it homepage sh
and launch the command from the container (i've installed curl package)
curl ​​https://healtchecks.io
or
curl --header "X-Api-Key: xxxxxxxxxxxxxxxxx" https://healthchecks.io/api/v3/checks/
it works correctly, but not homepage, perhaps because nodejs does not take the proxy environment variables.
How can I solve this?
Sorry for my bad english.

homepage version

v0.9.9 (6b1080a)

Installation method

Docker

Configuration

in docker-compose.yml:
environment:
      HTTP_PROXY: 'http://192.168.2.14:3128'
      HTTPS_PROXY: 'http://192.168.2.14:3128'

in services.yaml:
- Healtchecks:
      icon: healthchecks.png
      href: https://healthchecks.io/projects/xxxxxxxxxxxxxxxxxxxxxxxx/checks/
      widget:
        type: healthchecks
        url: https://healthchecks.io
        key: xxxxxxxxxxxxxxxxxxxxxxxxxxx
        #uuid: <CHECK_UUID> # optional, if not included total statistics for all checks is shown

I am also experiencing exactly the same error with the healtchecks widget on v0.10.1. I am not hitting the internet via a proxy though.

I can also successfully make curl requests to the healthchecks API from inside the docker container and get back successful responses, but when homepage makes the request it always results in the error.

Is there any additional troubleshooting you would like to me perform to help identify the cause of this problem?
