If you get authentication errors from your BOINC client when connecting to LHC@home, please check your BOINC client version.
LHC@home uses SSL for connections to https://lhcathome.cern.ch/lhcathome and really old BOINC clients may have problems. (BOINC 7.2 clients and later supports SSL.)
If you are unable to upgrade your BOINC client to a recent version, you may still connect for a while to our legacy site: http://lhcathomeclassic.cern.ch/sixtrack
Thanks for your understanding!
