Challenge

Failure when trying to access Enterprise Manager thorugh the web via https. The web interface of Enterprise Manager works with http, but not with https.

Solution

To resolve:

  1. Clear browser's cache, cookies, history files, SSL state. Make sure that static content is enabled in browser's settings.
  2. Make sure ports 9392 and 9394 are open.
  3. Go to the Internet Information Services (IIS) Manager console -> Sites and check whether the "VeeamBackup" site is started or not (%windir%\system32\inetsrv\AppCmd.exe also works).
  4. Then go to the Internet Information Services (IIS) Manager console -> Application Pools and check that VeeamBackup application pool exists and has at least one linked application.
  5. Go to Services under the Computer Management console and insure that Veeam Backup Enterprise Manager service is started.

In case of using IIS6:

  • Make sure anonymous access is enabled in IIS

  • Then recreate a self-signed certificate for https connection:

    • ​Use SSLDiag.exe tool which is included in the IIS Diagnostics Toolkit and is the recommended replacement for SelfSSL for creating self signed certificates:

  • Go to C:\Program Files\IIS Resources\SSLDiag and run the SSLDiag.exe tool with the following parameters: SSLDiag.exe /s:2 /selfssl /n:CN=Veeam Backup Enterprise Manager_server_hostname /v:36

(Download the tool from Microsoft at the link below if you need it: http://www.microsoft.com/downloads/details.aspx?familyid=7E42B310-B2D1-496B-8005-9D91782B9995&displaylang=en)

 If using IIS7:

  • Make sure anonymous access is enabled in IIS

    • Then recreate a self-signed certificate for https connection:

  1. Go to IIS7 Manager console

  2. Check the root of the tree

  3. In the middle of the screen double-click "Server Certificates" feature

  4. Check "Create Self-Signed Certificate" at the Actions panel

  5. Specify a name for the new certificate. Click OK

  6. Go to "Sites" -> "VeeamBackup" and "click Bindings..." at the Actions panel

  7. Highlight the "https" string and click "Edit...", then check a previously created certificate in the "SSL certificate" drop-down menu. Click OK

  8. Restart "VeeamBackup" web site using IIS7 Manager console

  • Go to IIS6 Manager console

  • Check the "VeeamBackup" under "Web Sites"

  • Right-click and select "Properties"

  • Go to "Directory Security" tab and click "Server Certificate..." at the Server communications section

  • At the "Welcome to the Web Server Certificate Wizard" click Next, then select "Replace the current certificate", then select correct certificate, and click Next

  • Check the root of the tree

  • Restart "VeeamBackup" web site or entire IIS using IIS6 Manager console, or restart IIS Admin service
