SAP HANA Connection Error

Hi, I am getting this error while refreshing the report from the gateway and the source is SAP HANA.

{"error":{"code":"DM_GWPipeline_Gateway_MashupDataAccessError","pbi.error":{"code":"DM_GWPipeline_Gateway_MashupDataAccessError","parameters":{},"details":[{"code":"DM_ErrorDetailNameCode_UnderlyingErrorCode","detail":{"type":1,"value":"-2147467259"}},{"code":"DM_ErrorDetailNameCode_UnderlyingErrorMessage","detail":{"type":1,"value":"ODBC: ERROR [08S01] [SAP AG][LIBODBCHDB DLL][HDBODBC] Communication link failure;-10709 Connection failed (RTE:[89006] System call 'recv' failed, rc=10060:A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond)"}},{"code":"DM_ErrorDetailNameCode_UnderlyingHResult","detail":{"type":1,"value":"-2147467259"}},{"code":"Microsoft.Data.Mashup.ValueError.DataSourceKind","detail":{"type":1,"value":"SapHana"}},{"code":"Microsoft.Data.Mashup.ValueError.DataSourcePath","detail":{"type":1,"value":"vhpbiph1db.hec.pb.com:30215"}},{"code":"Microsoft.Data.Mashup.ValueError.OdbcErrors","detail":{"type":1,"value":"#table({\"SQLState\", \"NativeError\", \"Message\"}, {})"}},{"code":"Microsoft.Data.Mashup.ValueError.Reason","detail":{"type":1,"value":"DataSource.Error"}}],"exceptionCulprit":1}}} Table: Billing Doc.

I do not get this error always it's just some days I get this error out of nowhere and another day the report refreshes perfectly fine, I have seen some post mentioning the same error but did not get any clear resolution. Can someone guide me from where can I start troubleshooting this?
