There are multiple possibilities:
1.There is no internet connection.
2.The activation id is wrong and not existing
3.There is a firewall and proxy settings are needed
Workaround / Resolution
A very simple and fast workaround is to use the offline activation.
Check network connection by calling these three urls:
If all of those are working, please check for an existing proxy connection by checking the Internet Explorer:
- start IE
- goto Extras
- goto network options
- goto connections
- goto LAN settings
If there is an automatic script or a proxy is entered, please use this configuration in the ZLAU as well. If the user do not have access to this data, he/she has to contact his/her local administration or use the offline activation.
