If you're on Windows or getting the error minus the "(attempt to index a nil value)" part, this solution won't work for you and you should start a different thread. In most cases it's caused by a network failure to connect to the authentication servers, usually cased by a firewall or anti-virus software.

This should be fixed complete in Lightroom CC/Lightroom 6.
