  • Select yes in the import windows.

• Opt-out of HTTPS on project creation

  Start a new project without HTTPS

  • Open console.

  • We can create a new project without HTTPS from UI as well.

    

• Disable SSL in debug mode.

  If we had choosed the “Configure for HTTPS” but actually we didn’t want to use it. We can use this method.
