After upgrading the Controller to 188.8.131.52, you may encounter issues where the SAML authentication request fails. These 4.5 Controller requests are being rejected by some ADFS IdP.
This affects Controller versions 184.108.40.206 and beyond that have accounts that use ADFS SAML IdP.
Create a shared local user and use the local login option to bypass the SAML login issue.
The 4.5.x hotfix for this issue is not released yet. Please hold off on any Controller upgrade until the hotfix is available.
The issues described will be addressed in the upcoming release as PLATUI-1227.
