Thanks for trying the new dweb-app (aka AutonomiDweb App) and taking the time to feed back. 
This is always helpful, even if problems are already known because your report contains other useful info such as “you tried this” and “you didn’t have any other issues” etc.
BTW you can resolve the issue by moving the SECRET_KEY setting from .bashrc to .profile. Putting environment settings in .bashrc only works for programs that are started by the shell (bash) but putting them in .profile works for all programs as it is read at login.
I suspect the Billboard issue is not you but the network, but don’t know for sure. It seems more likely, not least because you say it worked last week.
I’m glad you liked the improved experience.
