Dear Tomas,

There must be some restrictions to the internet connection. Please follow these steps and try to sign in again.

Add these exceptions to the proxy

  • *.bizagi.*
  • *.msecnd.*

Add these URL to the safe list in the firewall

Verify if Ad-Aware is installed. Uninstalling this program will resolve the connection issues.

Another solution is to add site in the Trusted Sites of your Internet Explorer. Please check these instructions for Internet Explorer 11:

  1. Open Internet Explorer, select the Tools button, and then select Internet options.
  2. Select the Security tab, choose Trusted sites, and then select Sites. You can add sites to the zone you chose, or delete sites that you do not want longer in this zone.



I have the same problem with version 3.4.1968. We followed the instructions of Juan Zuluga above. It didn't help, Sign-in-box remains blank.

There are lots of topics here with the same problem (empty sign-in-box). If you leave your customers alone with that severe problem, we can not longer use Bizagi modeler in our projects.

We request your support


Dear Andreas,

We apologise for the late reply. We are currently at version 3.8 of Bizagi Modeller, so I expect that the issue you were experiencing has been resolved.

I could not recreate the issue in the current version.

A new version was recently released, and you can get this from

Please let us know if this has resolved your problem, we look forward to your response.

Kind regards,

David Foster
