This KB July 22, 2025—KB5062660 (OS Build 26100.4770) Preview causes CSE service tunnels fails to connect.
Current Workaround: We need to un-install the "Microsoft KB5062660" so the CSE could establish a service tunnel connection.
However, we have escalated this issue to Sonicwall Engineering, this is being investigated.
