Orchestrator Is Receiving " Error Synchronizing New Update Versions " When Auto Update Policy Enabled

Continuously error "Error synchronizing new update versions received from: https://download.uipath.com/contents.jsonSystem.Net.Http.HttpRequestException: No such host is known. (download.uipath.com:443) ---> System.Net.Sockets.SocketException (11001): No such host is known." is thrown.

Root Cause: This kind of error occurs when there is an Auto Update policy enabled which is used to auto-update Studio or Robot components at any level on the Orchestrator.


Investigation Steps: Try to disable the policies by validating the below documentation and check if still receiving the errors.

Refer Auto Updating Client Components - Configuring Policies .

Due to the above function, Orchestrator will periodically communicate to obtain information about the updatable versions of Studio/Robot, etc. from the server (download.uipath.com).

An error will be recorded in the event log if the above communication fails due to an environment that cannot connect to the Internet.

Resolution:

Log in to the "host" tenant of Orchestrator as "admin" and disable the following settings,
  • Settings->General page: Auto-update settings for client binaries (Robot, Studio, Assistant, etc.) > Auto-fill available product versions.

Refer the Orchestrator - Configuring Tenant Settings Host Level .
