WebUI issue on BE3600

Hello,

One of my customer is facing a weird issue. The WebUI is not functionnal on his BE3600R3 appliance.

So I logged in the appliance using RDP to check if can see some event ... No event found (or maybe I missed them)

In fact the probleme is arround OpsCenter WebServer service and OpsCenter Server service. I am able to start them manually using opsadmin.bat or services.msc but they stop just 2 minutes later ...

Any idea ?
