Esri® announces the ArcGIS Web Adaptor (IIS) 10.8.1 Stability Patch. This patch resolves a critical issue with the ArcGIS Web Adaptor (IIS) 10.8.1 where network requests may begin to fail with a HTTP 500 error code, resulting in ArcGIS Enterprise becoming unresponsive. It is required to install this patch for any IIS-based web adaptor configured with the Portal for ArcGIS component of ArcGIS Enterprise. This patch deals specifically with the issue listed below under Issues Addressed with this patch.
This patch is required for any ArcGIS Enterprise 10.8.1 deployment that uses the ArcGIS Web Adaptor (IIS).
Important Note: A single installation of this ArcGIS Web Adaptor (IIS) 10.8.1 Stability Patch will update all ArcGIS Web Adaptors configured on a machine; no additional installation or configuration is needed for multiple web adaptors on a machine. You will observe some limitations with the tools used for finding and notifying of patches. The PatchFinder.exe is currently limited to only showing one web adaptor even though the patch has been applied to all web adaptors. The Patch Notification tool does not currently support showing patch notifications for the ArcGIS Web Adaptor.
