I wrote it clearly in my message: we users accept this support. The fact that it is free is not and should never be a justification for lower quality media or delays.
In this case, your support was very bad.
Whether it's Apache or Nginx, Drupal doesn't have an "admin" folder.
And already the first answer to the problem was provided after 2 days (more than within 24 hours).
More generally, I have noticed these delays not only with this problem.
However, I understand that you cannot know everything and try what you can to help out.
I wonder what is right, in the end, the link for installing an app with what is the redirect or some other problem related to this error situation.
I am very disappointed. Like other posts by other users who have not found a resolution or who were disappointed with Bitnami solutions, if I do not solve this problem I will remove and advise against Bitnami both with negative reviews and to my colleagues. Also because, if the pages beyond the homepage cannot be viewed, even if I wanted to, I can no longer adopt it as a solution.
