Unfortunately, this normally means there is an undetermined corruption in your AutoPass database (reference https://softwaresupport.softwaregrp.com/doc/KM03078906). This was mostly caused by a Microsoft Windows Update, but Micro Focus has yet been unable to determine the exact culprit.
First, try the following:
1) Clear the cache from the browser that is trying to access AutoPass.
2) Restart the AutoPass Windows service.
3) See if the problem persists.
Sad to say, this most likely will not fix the problem, and you will need to resort to the ''nuclear'' option of reinitializing your database (i.e., back to a default state):
a) Stop the AutoPass service.
b) Find your data directory and make a backup. Default location:
%ProgramData%HPHP AutoPass License ServerAutoPassLicenseServerdata
c) Within your data directory, there is a database directory. Rename this database directory.
d) Start the AutoPass service.
e) You will be back to a default state (credentials - L: admin P: password). Set your new password, log in, reload your licenses and redo any configuration as needed.
