Not able to connect the SMP Admin URL configured in Web Dispatcher

Hello Experts,

I have configured the SMP Admin URL in Web Dispatcher but when i am trying to access it. It give me 503 error.

I have also configured back end URL and they are working.

I have configured like this:

wdisp/system_2 = SID=SMP, EXTSRV=https://<SMP Server 1>:8082, SRCSRV=*:9082 SRCURL=/, STICKY=true

icm/server_port_0 = PROT=HTTPS,PORT=9082
