Please click on the Settings button in the login screen. Then change the Connection to Automatic. It might help because it looks at the general proxy connection settings for the internet connection. Even if you don’t know what the proxy settings are, this setting can discover the correct proxy settings.
Or to Custom Proxy Server (if you know the proxy credentials)
and then press Check connection button to verify if you can reach our servers.
Note! In older versions of FlippingBook Publisher you may not have this window. You will see a notification whether your connection is successful or not.
To delete this, please do the following:
- Press the Windows-key and the R-key at the same time.
- In the opened field type %temp% and press Enter.
- Find the CachedServiceDiscovery.xml file
- Close all Publisher windows
- Delete the file
- Start FlippingBook Publisher again.
This helps because the file contains connection settings that are specific to a particular edition of Publisher. In some cases FlippingBook Publisher doesn't recognize that this file contains settings that are for an older version. This makes the connection fail. For instance it happens sometimes after upgrade.
If you’ve followed all the steps and still cannot connect, then something is still blocking the connection to our licence server. Contact your IT administrator and show this article.
