failed to create gateway in On-premises data gateway

Hi, 

Check your proxy config and are you using the latest GW? if not then MS suggests that you use the latest version of the GW. 

Refer: On-premises data gateway "Failed to create gateway. Please try again" - Microsoft Q&A

yes GW is latest,  HTTPS mode in gateway is enabled and what other think i need to check its a windows VM. If you help little bit.

Hi 

1. You might receive this error if you’re trying to install the gateway on a domain controller. Deploying on a domain controller isn’t supported. You need to deploy the gateway on a machine that isn’t a domain controller.

2. You might encounter installation failures if the antivirus software on the installation machine is out of date. You can either update the antivirus installation or disable the antivirus software only during the gateway installation. After the installation is finished, reenable the antivirus software.

3. This error could be due to proxy configuration issues. The gateway log provides more details for troubleshooting. For more information, go to Configure proxy settings for the on-premises data gateway.
