Networking ::: Can't connect to app's HOST_INTERNAL using Twingate

INFORMATION

Relevant information to this issue:

To manage access to internal resources I use Twingate and I have Twingate up and running. Twingate connector is in the same environment running as all the apps/resources that I want to connect to. At the moment I have my database as private and I can connect to the database through the Twingate Tunnel with no problem.

ISSUE

But when I want to connect to a private application I can’t reach it

Is there something network-wise that is different for applications than for example the database that I can connect to? Or is there something I’m missing that I can’t see yet?

HOW TO REPRODUCE

Describe step by step how to reproduce the issue
Setup Twingate and try to connect to application.
