## Description

### Steps to reproduce

It appears when you are navigating the software.

### What is the buggy behavior?

  - When requests are cancelled during quick navigation or network timeouts, the user is shown an unknown error message

### What is the expected behavior?

The expected is there would be no message error as the message is not useful to the user.

### Important note

I found something similar written in <mention class="mention" data-id="38805" data-type="work_package" data-text="##38805">##38805</mention>
