Connection Error with On-Premises Data Gateway

Hi, Leonardo8182 

Before reconfiguring the gateway, first make sure that the previous gateway has been completely uninstalled:

Then re-download the gateway installation file:

Power BI Gateway | Microsoft Power BI

During the installation process, make sure that the antivirus software is turned off:

I just recently started to get the error "Watch dog failed to start process" and this was not after any kind of update or reconfigure. Before I attempt an update or to reconfigure, what is the watch dog process? Is it related to the gateway service? When I search for that short version of the error string, "watch dog failed to start process", this particular article is the ONLY result. If I search for "watch dog service", I see suggestions that this is fake anti-malware. Interestingly, this just started happening recently and we are using a rather old version of the On-premises data gateway.
