PDU Web Page Acces Fail

[IslamFouad]

I have a project which the customer have PDUs (AP8886), these PDUs we have worked with along time in other projects and we didn't face this problem before 

which is, some of these PDUs maybe 25% of them when i configure the Network settings using Device IP Configuration Utility software and after the PDU have a Static IP address the web page shows no access to the device Ias shown in the attachments) this appears in only 20-25% of the quantity in the project and unfortunately we need to acces the web page to resume the configuration or to view the data or the logs.

AOS v6.8.2 App v6.8.0

can anyone have any recommendation or a solution how to view the web page or even why this happen!

Hi

Would it be possible to telnet/ssh into the unit, check if HTTP is activated and then try logging on with HTTP instead of HTTPS?

If you are able to log into the interface using HTTP only, I would suggest creating a new self signed certificate on the unit.

This is done by navigating to [Configuration] -> [Network] -> [Web] -> [SSL Certificates] and the choose "Remove" and "Apply". 

This done, reboot the NMC via [Control] -> [Network] -> [Reset/Reboot]

Once there, please check that only the "Reboot Management Interface" is chosen before pressing "Apply"

This will force the NMC to generate a new self signed certificate and possibly get HTTPS back in working order.

On a different note, it might be worth it to upgrade to last firmware, as there a a long series of security fixes that has been implemented since 6.8.2/6.8.0.

You can find the latest version 7.0.6 here ->

Hi

first of all thank you for your quick reply really appreciate alot

today very early in morning i thought of that and i accessed the PDUs SSH and i found that the HTTP is disabled and the HTTPS is enabled so i enabled the HTTP and now i accessed them in WEB by HTTP only and i configured all of them but still cant be opened by HTTPS

i have around 600 PDU so i can update this firmware version on the DCE server to update all of them by Mass firmware update through DCE if this will be better overall, but i will need the .xml file for the Updated firmware ofcourse to update the version on the DCE server.

ThankYou

Hi

In regard to the updates, I believe the firmware catalogue has just been updated.
If your DCE has access to the internet, it should update automatically, but you can download it manually as well -> https://www.apc.com/shop/us/en/products/DCE-Device-Firmware-Catalog-File/P-SFSWCDFCF

As the the actual issue:
Is this a new issue, or has the setup been working with HTTPS previously?
Is the issue present when using a different browser, f.ex. Chrome?
Last but not least it might be worth it, testing directly from a laptop to the PDU, as this will help in identifying network based issues.

In this type of case, there is a multitude of possible root causes, and at this point it could makes sense to contact your local CCC and get a case going.

Thank you for sharing theupdated file with me

first of all i'm working from my laptop directly to the PDU, secondly this issue is new for me i didnt face any PDU which couldnt open by HTPPS specially that the HTPPS is enabled on these devices, with these PDUs i tried Internet Explorer which gave me this screenshot shared in the original post & also i tried Chrome which gave me (this site cant be reached) as if there's no device with this IP address connected to.

Now if i faced a PDU with this issue i'm enabling the HTPPS through SSH and then configuring the devices through HTPPS web interface and everything is okay, but this case is very strange to me why the HTPPS is not working for these PDUs

specially i checked the internet options through Internet explorer and the TLS 1.1,1.2 & 1.3 are all enabled and it's supposed that everything is okay.

Hi

I believe the best next step would be to download the support file from the PDU and open a ticket with your local Customer Care Center. As I mentioned, there is a multitude of possible causes, and getting the support file to the right people for analysis would be your best bet at this point.
