I got this OEM R730xd and trying to access iDRAC web UI but to no avail. This idrac has an enterprise license, I changed the network IP settings (set to static and also tried dhcp), I can ping the server afterwards but still can't access the web UI. Firmware are also in the latest versions, for this server - idrac is using v2.82.82.82, BIOS is v2.13.0. Also, I did an idrac reset to default factory defaults.

I did some googling and someone suggested that the webserver is probably disabled and might have to enable it using racadm command. I downloaded the tool from this link: https://www.dell.com/support/home/en-us/drivers/driversdetails?driverid=9dd9y and ran it on a remote PC with this syntax:

racadm -r -u -p set idrac.webserver.enable 1

even though I can ping the machine, re-checked the credentials I'm using, I'm getting this error:
ERROR: Unable to connect to RAC at specified IP address.

I cannot also access idrac via ssh.

Not sure how to proceed at this point, any ideas are appreciated.
