Solid blue light on C-5

[sandbender]

Hello! I'm new to Hubitat, inherited a C-5 from my cousin. To the best of my knowledge it was working when he sent it to me.

When I fire it up on my network, it comes up with a solid blue light. It gets an IP address, but when I attempt to connect to it via https, it says connection refused. Tried multiple browers, incognito mode, no joy.

http://[hub.ip]:8081/ loads this Hubitat Elevation Update Tool

Select one of the following versions to switch to:

But the list is blank.

I tried going to http://[hub.ip]/hub/cloud/updateDiagnosticTool in regular Chrome and incognito, also tried Firefox, same result:

This site can’t be reached, refused to connect.

Reset page shows:

Platform version: blank
Hardware Version: Rev C-5

Any suggestions appreciated!

[SOLVED] Blue light of death on C5 with old Diagnostic Tool

I have a C5 hub and up to 12/1 it was rock solid. I do not know why but the hub cannot be discovered on my local network. I looked in the community for help on the error and found some things to try.

I tried to load .145 then back to .148 but either time it never loaded. I went to (my IP):8081/setup and it never found my hub. I verified it is connected to my r…

Thanks, I had already followed the steps in that thread, but it looks like the platform is gone. I'll get a new one.
