Cannot start vCenter: 503 Service unavailable

Jump to solution

Hello!

 

I got this message above from web browser, while I try to connect to vCenter:

503 Service Unavailable (Failed to connect to endpoint: [N7Vmacore4Http20NamedPipeServiceSpecE:0x000055816a6c0720] _serverNamespace = / action = Allow _pipeName =/var/run/vmware/vpxd-webserver-pipe)

 

And I have this image from shell that shows which services have started (attached)

 

 

There are like many solutions online, but I do not know where to start...I also found some articles that looks like with my problem, like certificate, but i dont know if is the same.

 

I appreciate your time trying to help me

cm.log says it is down from 2nd July 2022. I suppose it might be better to re-install VC.

Which vCenter Certificate are you using? highly possible that the certificate has expired. 

a few weeks ago I have had the same issue. After the Certificate renewal issue has been solved. 

Please remember to check the certificate template in CA - it should be slightly adjusted for vSphere7.

Hello !

I've tried to renovate as much as user root and user: administrator, but it's showing wrong password.

I've reseted the password both.

How do I see which certificate vcenter uses?

 

Thank you!

there are a lot of articles on the internet on how to check and configure it. 

you can also check Certs with WinSCP or via SSH 

 

on your screen you have the wrong username; not root - only should be [administrator@vsphere.local]

The system tells you to provide a username: so you should provide ...administrator@vsphere.local

to ssh you log in with [root] but all replacement actions and confirmation is going via administrator

 

One more thing - you can reset all certificates with action number 8 - but before do a snapshot; 

once it will be reset - you will be able to login to vCenter 

after that you will be able to check and decide what to do next

run the command:  /usr/lib/vmware-vmdir/bin/vdcadmintool

A new password is generated (automatically)

I've tryed copy and paste and to type too, both show "incorrect password".

This is the error (above) that happens, so therefore I unable to regenerate the certificates.

I have no idea why your password is not accepted. Please check the layout in notepad. If password is the same

Hi,

First you need to reset the administrator password. Otherwise you cannot renew the certificates

I assume so. Is it your vCenter in Canonical name? 

What is the current status? Have you progressed slightly?

I am still wondering, why are you not able to login with your admin credentials to vCenter. 

When you will download vCenter ISO and will attach it to your mgmt windows VM - check Recover/Repair option. 
Maybe there will be option regarding certs. 

I will check it in my lab too. 

Without admin password you will not be able to proceed.
