Our Enterprise Gateway fails with the error "Unknown error in Enterprise Gateway" (see below ) it is connecting to our on perm SSAS Tabular model and fails after a 30 mins to an hour of normal usage.
We recently installed Power BI Enterprise Gateway (moving from Power BI Analysis service connector which is now uninstalled)after which the Power BI fails with the following error "Unknown error in Enterprise Gateway" Error Code DM_GWPipeline_UnknownError, Moreover we could not see any event log for the Enterpise Gateway logged. The on prem analysis service remains functional but the gateway errors out. If we restart the analysis service server the enterpirse gateway becomes functional and Power BI works fine for 30 mins to an hour works and error repeats.
P.S: We checked the ports and all are working fine.
