We have the license server for QuartusII tools falling down (1719@lamipc54.epfl.ch)
You can change in your configuration with:
QuartusII --> Tools --> Licence SetUp --> 16000@edalicsrv.epfl.ch
or with environment variable:
LM_LICENSE_FILE=16000@edalicsrv.epfl.ch
Available on VPN only or in the EPFL site.
Best.
