To access the page, you need to go to the <mark style="color:red;">gateway</mark>, port <mark style="color:red;">2500</mark>\
If the system is running locally, then <http://localhost:2500>

It is impossible to test frontends, user interfaces directly without using the gateway port.

{% hint style="warning" %}
**Why is this?**\
\
This occurs because the frontends are configured to go to the same port. When opening the frontend without the gateway, the application tries to access the API, but this will not work due to the different port
{% endhint %}

Databases and APIs will work fine
