Upstream connection error: reset due to connection failure before headers

Hey guys, newbie to the forum here. I recently setup a ce version of Nutanix in our work lab environment on vsphere. Up until last week I was able to log into the gui, I can still login via putty.When I try to log into the gui now, via xxx.xxx.xxx.xxx:9440/console/#login - I get the above message.I have also had the message "server is not reachable”I did think about trying the install again but thought I would ask the question first and see if anyone else has had the same problem and if so how they got around it?  Thanks in advance.

LCM update of Foundation 5.4 consistently fails

Using LCM to update Foundation to version 5.4 I am finding that it consistently fails on Lenovo hardware.I’ve tried two clusters so far that were both at AOS version 6.5.2 but both LCM updates of Foundation to version 5.4 failed.Ominously there is mention in the Field Installation Giude for Foundation 5.4 (link below) that “Software Update” should not be used to update Foundation on Lenovo platforms, and advises to use the command line instead.It worked when using the command line, so my question is: what’s going wrong when LCM attempts this?https://portal.nutanix.com/page/documents/details?targetId=Field-Installation-Guide-v5_4:fie-upgrade-foundation-vm-c.htmlWhat tends to happen is that most nodes except 1 or 2 are successfully updated, with the remaining node neeing to be done by hand from the command line.

Nutanix storage containers (selfservics vs default-...) - which is for what?

HiNutanix 6.6.2.5What is the difference for the following storage containers, except the replication factor, compression, etc..) ?  I mean what is meant to be placed for the certain containers.For example, when I deployd Prism Central, then there was an option between “default-..” and “SelfServiceContainer”, so my question is, which is for what (images, VM’s, etc..)..?Thanks.RegardsRaul

Alert reappears without pressing the Resolve button

Hello Nutanix expertsI have a question for youAmong the functions of Nutanix, the alert is known as a good function that can immediately inform the status of the clusterAs far as I know, if you don't press the resolve on the prism, the alarm that occurred once will not recurThrough the filter of the alert, I checked if I pressed auto reserve or manual reserveIs there a reason why the alert occurs again when it is not applicable to both options I'd appreciate it if you could explain it ============================================================================For example, a routine inspection conducted in the previous month asks the customer to confirm that the alert is a new alert because the alert has been reactivated even though the customer is aware of it

Nutanix Rest Api V3 - Webhook Custom Parameters

I’ve been trying to create webhooks using Nutanix API V3 (using Nutanix API explorer) and it works fine. The only problem I’ve been getting is to send some custom parameters along with the payload. Let’s say I want to send a custom parameter named cluster ip and value is “10.247.xxx.xx”. It’s just an example, but I want to receive this custom parameter whenever the event is triggered (so basically send this when event is sent to my webhook URL).  I’ve tried googling it but no use. I cannot seem to find anything in documentation as well. Is there anyone WHO can help me with this?

Hello, I understand that if the node fails, the ha function is activated and attempts to recover. If one node fails in a Data Resilience Status Critical state due to a lack of storage space, will the cluster collapse? What happens.
