I can create scene but not able to run the the GUI. Following is the message in kernel. Can anyone please support?

It seems to me that it's failing when it's trying to download the EPW file. This often happens when running inside of a server or VPN that has firewalls or some other restrictions.

To test can you please try pre-downloading a TMY or EPW file and instead pointing the GUI to that location? (read the EPW, not 'get' the EPW).

This appears to have been solved and I'm closing this. Please comment back and reopen this issue if the problem hasn't been solved. Thanks!
