I have an error connecting to older version of ArcGIS Portal (10.9.1) from latest version of FME Form/Flow (2023.2.1 b23774). Does anyone know how to resolve this issue?

I have resolved this issue by downgrading FME Form/Flow to 2023.1.2 version, but ultimately that was not the goal. During the research I have found that old version of ArcGIS Portal might be the issue (client is due to upgrade their ArcGIS Portal soon and I will update this post accordingly).
