In Acunetix v11, the user interface is web based, and by default the web server hosting the web application is running on port 3443.

Therefore, if you are logged into the machine running Acunetix, you can browse to https://localhost:3443 to access Acunetix.

If you need to access Acunetix from a remote machine, you will need to know the IP address / hostname of the machine running Acunetix. In this case, you can access Acunetix by browsing to https://<IP or Hostname>:3443>

  • I was using Firefox and got the error “A connection to server could not be established. [Status: -1]” each time I updated Acunetix.

    I solved the problem by deleting the security exception (regarding the certificate) that was previously set in Firefox , reloaded the URL and set a new exception.

    • Hi,

      Can you check that you are using the latest build of Acunetix. This is 11.0.173271618.

      Having said that, Acunetix does register the Acunetix Certificate in the OS’s certificate store. Unfortunately, Firefox uses its own certificate store. This might cause the problem that you have experienced.

    • can you re-install and use another custom PORT that worked for me

      • Hi,

        You can change the port used by the UI from C:\ProgramData\Acunetix\settings.ini. Change the server.port setting to the new port and restart the Acunetix services.
