I am experiencing an issue this morning with the following error message in Synthiam ARC:

Version: 2025.06.22.00

System.Net.WebException: The request failed with HTTP status 417: Expectation Failed.
   at System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall)
   at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters)
   at ARC.com.ezrobot.www.apps.WebService.GetPlugins(String[] GUIDsToIgnore)
   at RKUcwiabYs6XhKUTStt.KPjB6PauHWtitgrdWKh.Hega6YVqvW()

It seems to be related to a web service call while trying to fetch plugins. Could someone help me understand why I'm encountering an HTTP 417: Expectation Failed error, and how I can resolve this issue in ARC?
