While logging in to LF forms/LF Web Client using "windows authentication" button on login page, an "error occurred" message is displayed. There is no corresponding log details on event viewer. Recently there has been a windows server update and reckon this may be due to the end of support for TLS 1.0/1.1. The interesting behavior  post the server update with either of the web component is that, the user can login to either of them if their windows credential (Domain\User Name) is manually typed in and sign in button is clicked. Logging in using The windows authentication button was working previously (before the update).

Please let me know if there is  a known issue/work around/resolution available.

Thank you.
