SGPUW1 and SGPUW2 are only accessible via SecretLab VPN. Download SecretLab VPN profile from Nextcloud, install the profile on your client device, and then connect to SecretLab VPN before attempting to access these GPU servers.
Note: SecretLab VPN does NOT tunnel your Internet traffic, only the SecretLab VPN subnet traffic is routed thru it.
If RDP or SSH fails to connect, remember the first thing to check is if SecretLab VPN is connected or not!
