Access to the /about page was redirected

Must-share information (formatted with Markdown):

  • which versions are you using (SonarQube, Scanner, Plugin, and any relevant extension)
  • what are you trying to achieve
    Without login, I want to visit the /about page and see the public project
  • what have you tried so far to achieve this
    I don’t know how my sonar is affected. When I visit / about, I am redirected to /sessions /new?Return_ to=/。 So I can’t see the public project page.
    1、I tried to reinstall sonarqube7.8, Visit /about was not redirected
    2、I tried to find it in the official help documentation and /conf/,but I couldn’t find the possible cause of redirection。
