[FIX] A website is requesting authorization

Applicable to:

  • Plesk 12.0 for Windows
  • Plesk 9.x for Windows


It's impossible to access website - authorization prompt appears.


There may be several reasons of this issue. To determine them, the following conditions need to be checked:

1\. There should be read + execute permissions for IUSR\ <ftp\ user> on the domain index page.

2\. Root directory for the domains can be under Parallels Plesk Panel protection.

3\. Passwords for system user and IIS user can be out of synchronization.


  1. Go to %plesk\_vhosts%\\domain.com\\httpdocs directory and check permissions for IUSR\ <ftp\ user> account.

2\. It can be checked using Plesk Control Panel. Go to Plesk, domains, domain.com, Protected URLs .

3\. The password for IIS user can be synchronized using the following command:

    "%plesk_bin%\\websrvmng.exe" --update-anon-password --domain-name=domain.tld

Note: this feature is available starting with Parallels Plesk Panel 7.5.4 and the latest hotfixes.
