I am having issues with my hub loosing connectivity to all devices and the ability to login to the web interface.
When this happens all actions stop working, the hub is unable to be accessed. The only way to fix it is to power cycle the unit.
Once a power cycle is completed the hub will work again for a few days to a week, then recreate the same issue causing us to power cycle it.
Any solutions for this or do I have a hub that is failing ?
Sadly, I have that, too. The green light stays on but the hub is frozen, can't even ping (so no interface to the hub or maintenance page is possible). Sometimes it stays up for weeks other times (like this weekend) twice in 1 day. No programming/device/app changes were made, jumbo frames have been disabled, new power supply, all the things to look out for have been checked. The hub just dies with nothing in the logs, it's quite frustrating as a smoking gun still has yet to be found. I'm hoping the next gen hub (C-9?) will not suffer from the same issue.
Yes these are the exact same issues that I am experiencing, I just didn’t explain it as well.
I’m able to unplug mine and reset it to fix it but it’s frustrating that all devices freeze and we have to power cycle it.
Welcome to the Hubitat community, sorry you are having troubles.
What specific hub firmware version are you on? There have been many updates in the past couple months to address issues like this.
Have you done a rebuild database lately? That can help if a database is corrupted due to pulling the power cord or other unintentional power loss. Generally speaking, you never want to pull the power plug on a Hubitat or any computer for that matter.
The next thing you want to consider is if there are errors or warnings in the logs. That may direct us and/or support to an issue that needs to be addressed.
Please also read this and try the steps listed.
For my case, I'm on the latest version .197. And I have a routine setup to reboot every week (that has been in place for years) which seems to have helped. I just ended up living with it and hope I get a week before a crash so that the weekly reboot keeps it going.
Could you explain how you setup that routine ?
I have never thought about that.
I make sure that I keep my hub updated regularly.
I have a node-red setup that does that externally using the hub's reboot URL. But there is a Hubitat app you can use in the hub,
[RELEASE] Hub Rebooter App.
What hub model?
If you didn't do so already, I would create a warranty case. Based on details provided you may be dealing with a hardware malfunction: Warranty – Hubitat Support
Hi @bobbyD, I have a C-7.
Bobby, I have a c-8
I did look at the warranty form, I haven’t filled it out. I have had mine for over 90 days. The way I understood that form I wasn’t sure if I could fill it out.
Yes, fill it out. It will get the process to get your hub's engineering logs viewed.
