First time booting C-4 hub

I submitted an email to @support but didn't get a response, so I'm trying here.

I bought a C-4 hub a while back, brand new. I'm finally trying to get it setup, but it never shows green. The light stays blue. When going to the 8081 link, I get a message about versions to switch to, but no options.

I'm guessing that the hub ships mostly blank and it needs to download the first version to be useful.. is that right? Is the C-4 version not supported anymore?

How do I make use of the hub? Is it just a paperweight now?

Thank you,
Tim

That’s actually normal for a C4. C5 and C7 hubs turn green after the platform loads.

Sounds like something could be wrong nonetheless, but FYI the LED color isn’t a clue in the case of a C4 hub.

The C-4 does not have a green light, just red or blue, so blue could be a normal state for that hub. (Though just to be clear, if you bought a C-4 new, it would have likely been before spring of 2019, when the C-5 was introduced.) It should still work, so you may need to wait to hear back from support on why not if it isn't. Otherwise, I'm assuming you've at least given it a few minutes to download firmware? New hubs used to ship blank (current ones should have some firmware).

Thanks for the reply. Yeah, it's been a couple days. I can't reach the device outside of port 8081.

I've tried power cycling it and it doesn't seem to make a difference.

Ok, hopefully support can help me resolve it.

Follow these directions to get the latest diagnostic tool and then you should be able to download the latest hub platform version afterward.

I've tried that, but my system doesn't have that diagnostic Tool location.

When you're navigating to [your hub IP address]:8081, you are navigating to the diagnostic tool. Go there and post what version yours is at please.

Ahh. Ok. It doesn't have a version number anywhere on screen and I checked the source code, no hidden version number included.

Copyright 2018 if that helps.

Did you try browsing to http://[Your Hub IP]/hub/cloud/updateDiagnosticTool as the documentation page mentions?

Yeah, I've done that several times. It gives me the same connection refused message.

Really, just port 8081 connects. Nothing else seems to connect.

@tim.w.newsom Since you have a new C-4, your issue may be related to the link below. Not saying there's a fix here, but it's a likely explanation. If I remember correctly, support may need to do something on their end, but the hub should ultimately work. I'm almost positive there was another post somewhere saying how to handle this if the hub was never registered, but I can't find it now.

Great! That helps at least understand it, maybe. Lol

@gopher.ny might know how to help.

So, in Chrome dev tools, I can modify the web page that has the updater versions. If I knew the right code to put there, I could hack a submit that might perform the update.

But, that's pointless if the hub can't connect to cloud services in order to download the update.

I could host the update on my internal network update my internal dns so that it points to it... but I don't have the update file to host. Lol

Probably will need to have support help me resolve it.

Lol. There’s no reason to hack anything. Someone will reach out soon and get you on your way.

Sorry for this dumb question, but you did substitute your actual IP address for the brackets and where it says your IP, correct?

E.g. http://[Your Hub IP]/hub/cloud/updateDiagnosticTool

If your hub IP address was, for example 192.168.1.2, then the URL for you would be...

http://192.168.1.2/hub/cloud/updateDiagnosticTool

In that case, I guess I won't recommend the universal solution of rebooting. :slight_smile:
