Error message "407 Proxy Authentication Required"

[rafaelbianchifotovoltec]

Hello,

I have a question: How do I insert my proxy server address in the Bifacial Radiance main control? I'm asking you because everytime that I simulate my Scene, the console window shows the following message "407 Proxy Authentication Required". Thank you in advance. Waiting for your answer.

Thanks for posting -this is a new error for me, and seems to indicate a web connection error. Could you please copy-paste the exact error message and traceback to see where in the bifacial_radiance code it is arising? It may be coming from epwfile = demo.getEPW(44, -110) which goes out to the internet to pull an EPW file.

Thanks for your message. Well, follows the error message and traceback for you analysis.

OK, thanks. This is an error related to getEPW, which requires internet connection. Sometimes your work computer has a firewall that blocks internet connection for Python applications to minimize virus risk. You can either work with your IT department to get a firewall exception for Python applications, or manually download the EPW files using the energyplus website here and put the files in your \EPWs\ folder for your bifacial_radiance simulation.

Todo: meaningful firewall error message for urllib3 exception with suggestion to manually download data .
