the Unknown Error is about the logging in S4L right?
Because i got this big nickname that it even fit in the login Username lol...
Yeah, there is another "Unknown Error", the first one has been a problem since the migration and was caused by multiple PSG accounts being migrated into a single Aeria's account.
This issue how-ever is different, and we're working on it to provide a solution ASAP.
More information will be available in less than 12hours, and maybe even a fix.
