Hi.
What version of the eBook are you using?
We have a section in the eBook showing how to fix that issue.
Check page 190.
Let me know if that solves the issue.

Hi.
The latest version is 2.2. You can download it here: https://rntlab.com/module-1/welcome-build-web-servers/
Then, read pages 188 to 190.
I recommend using Option number 2 or number 3 to fix the issue.
Let me know if you could download the new version and fix the problem.

Sara
