The problem to connecting to the license server can happen for a number of reasons.
Autodesk servers could be temporarily down, if this was the case and it happened for a long duration of time then you would see a lot of movement within the community forums about it. For the most part the servers being down is temporary. In most cases it'll be back up and running within the day.
Other reasons could be;
- Security vulnerability that requires a licensing hotfix
- Network connectivity blocked by a proxy server
- Trovi or WAJAM preventing connection to the licensing server
If this does happen again and you can't connect create a new post and we can continue to troubleshoot.
Thanks.
