How do I use custom ports for debug service?

[rishabkshk]

When I am setting up the debug service with default ports, it errors out that the port is in use or invalid. That is correct as I have apache server running on 8005 already. To use another port I updated the DebugService.env file for DBGSRV_PORT=8091 and DBGSRV_SECURED_PORT=8092 and other combinations of different ports(kept DBGSRV_PORT=8001) . But still I am not able to get it working. Below is the error I receive.

EQARD1006E The Remote Debug Service daemon failed to start because port 8091 is invalid or in use.

Any leads?
