Issue
After restarting K2 server, the following error shows when attempting to login:
The type initializer for ‘SourceCode.Security.Claims.Sts.Shared.Authenticate’ threw an exception
Resolution
If you did not make any changes to your K2 environment recently, and this did not appear before the restart, then try performing a IISRESET first and see if that resolve the issue.
If you have made changes recently, such as applying a FixPack, and this shows up immediately after you applied a FixPack, you can check out this KB for the resolution step.
If none of the above works, please log a support case to request for assistance.
