User may get following message during report sync in HTTPS configuration

"GINESYS Report engine not yet configured or service is not running. Please get in touch with your administrator or call GINESYS helpdesk."

Check application API debug log file with following errors

Ginesys.App.Controllers.ReportManagementController [CompareReportXMLFile] - Return From REPORT Server : RequestEntityTooLarge and Request Entity Too Large
Ginesys.App.Controllers.ReportManagementController [CompareReportXMLFile] - Error in https://<>/GinesysReportUI//SaveXML.aspx

Setting uploadReadAheadSize in applicationHost.config file on IIS7.5 has resolved HTTPS issue.

Because during client renegotiation proces the request entity body must be preloaded using SSL preload.
SSL preload will use the value of the UploadReadAheadSize metabase property, which is used for ISAPI extensions

1. Run command prompt as administrator and set current directory as C:\Windows\System32\inetsrv

2. Set value as uploadReadAheadSize 10MB with following command

C:\Windows\System32\inetsrv>appcmd.exe set config -section:system.webserver/serv
erruntime /uploadreadaheadsize:10485760  /commit:apphost
