Grafana and google spread sheets using a proxy in windows

Hi, Im new using Grafana and I`ve been trying to display some data from Google spread sheets but the following error comes up.

Get “!A(MISSING)B13”: dial tcp connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

I`m guessing it has to with the problem has to do with the proxy im working behind.
I already have my HTPP and HTTPS variables setup on windows and the API key configured on google sheets but somehow it looks like grafana can not make the connection.

Is there any other configuration i must do on grafana to make it work??

Thank you
