As mentioned, “too much connections” can cause the websrv not to get reports due to a long queue of clients sending data at once. To control it, and manage the number of reports, please add the below lines (1 new) to "C:\gytpol\data\WebSrv\websrv_config.json" and restart gytpol WEB UI service:
"throttledUrls": {
"/upload/rsop/endpoint_report": 20,
"/upload/analyzer/host/get_task_list": 20
},
