Hi, I've just installed Feko 2021.2 for linux on Ubuntu 21.04 according to the Installation Guide available with the download. I then run $INSTALL_DIR/altair/feko/bin/feko_launcher and once the GUI shows up I go to Utilities->altair license utility to set up the HHWU license I have. On the almutil window I select Hosted HWU and enter the Authorization token I get from https://connect.altair.com. After clicking the Authorize button an error pops up saying "Unable to authorize with Hosted HWU system." Could please sb help me? Thanks
