Hey @Cal ,
It looks like the issue is with your system; it is unable to reach outside networks or is firewalling ports.
You can see this topic for a similar error message (though in that case the issue was on the server side, in this case it looks like a firewall issue on your end):
You could try running redbiom directly (per that topic) to get a full error log to use for debugging, and discuss with your system admin to see if they can identify the connection issue.
