503 Service Unavailable + unable to connect to appliance

[R1chou]

Hello,

Vcenter appliance version 6.7.0.44000

I wanted to add a second DNS address to my Vcenter appliance.
I'v added it going to my vcenter in console mode.

Since I did it, I can't no more connect to my vcenter, I have the following error :

503 Service Unavailable (Failed to connect to endpoint: [N7Vmacore4Http16LocalServiceSpecE:0x00007fe7ac017340] _serverNamespace = /ui action = Allow _port = 5090)

Second issue, I can't no more connect to https://X.X.X.:5480

When I try to login I have the following message : Unable to login

 I don't understand.... Do you think that a restart will help ?

Regards,

Hello,

Update :

I tried to restart my appliance.

It is still not possible to connect to the webclient, this time I have the following error : Connection has failed

I'am able to connect to VAMI during 1 minute then it stop to work.
I saw in ssh that the service applmgmt it's not running.
I tried to start the service but I have the following errors

service-control --start applmgmt
Operation not cancellable. Please wait for it to finish...

I've changed my root password but it doesn't change nothing.

Aside from the fact that what you did is most likely not supported, please explain - in details - what exactly you did.
Be prepared to restore the vCSA from your last backup.

I've explained what I did.
Just wanted to add a secondary dsn from my appliance vcenter console.

Since I did that my vcenter doesn't work.

I tried to delete my entry but it doesn't change anything.

Do you think that this kb could help ? https://kb.vmware.com/s/article/59476

I don't have entry for 127.0.0.1 in my hosts file.

Solved by adding the loopback address in the hosts file.

Not a good thing when services start being picky.. You might as well try a restart if you haven't done so yet.

If it doesn't fix it try to revert the change and take it from there.
