Laptop swap confusion

Hi All,
I’ve had HA supervised on an old laptop now for a couple of years, working great (mostly) - Recently aquaired a more up to date laptop and decided to migrate to the new one. Installed new copy of HA Supervised and restored from the most recent backup - All working ok except none of my Grafana dashboards are working, all the graphs are saying ‘No Data’ - Am I doing something daft and missing the obvious here?
Any pointers?

So Grafana is working?
What is the source it’s getting the data from? Has it’s IP changed?

It’s suddenly all decided to work ok! Thanks for your input though
