Unable to resolve hostname '<em>opencti</em>' in all the connectors

[Gitlinkerr]

Summary

I'm trying to use opencti behind a work proxy, so I followed the instructions given in issue #374 and #116, only to be confronted with **>\nDescription: Unable to locate the server named \"opencti\" --- the server does not have a DNS entry.** and this is happening to every connector even the import/export related ones.

steps to reproduce

1. open the docker-compose.yml
2. add HTTP-PROXY HTTPS-PROXY NO-PROXY to every environment variable of the connectors( I only added those to the connectors not to the other images (redis, opencti, elasticsearch))
3. create a network called opencti-network
4. add the connectors to the 'opencti-network'

expected behavior

I expect for the connectors to start pulling data

Actual behavior

0% cpu usage with >\nDescription: Unable to locate the server named \"opencti\" --- the server does not have a DNS entry.
