The browser based authentication dialog failed to complete. Reason: The download has failed

Hi Anonymous 

First, check the tips "Troubleshooting the On-premises data gateway"

"You may encounter installation failures if the anti-virus software on the installation machine is out of date. You can either update the anti-virus installation, or disable anti-virus only for the duration of the gateway installation to complete, then re-enable anti-virus."

If it doesn't solve after checking and testing with the help of these tips,

You could follow this guide to check network on your side, then delete on-premises gateway from the folder and follow the official document to download and install the gateway.
