Local backup failed, Leap Year?

[arnb]

This appears to be a Chrome based browser issue that I now have working with Vivaldi and Chrome as follows:

1. In Url bar enter vivaldi://flags or chrome://flags
2. in "search flags" field, enter insecure
3. Enable "Insecure origins treated as secure" then
4. Enter http://your hub's ip address
5. Click "Relaunch"
