Unable to Access vCenter on a Browser

Jonh_t — Wed, 12 Oct 2022 06:12:09 GMT

Hi VMware Community,

I am having issue accessing my vCenter via browser.

I am able to ping the IP address and I was able to access it few days ago.

May I know what I need to check for me further investigate causing the issue.

Thank you

I am using version 7 and yes port 443 is enabled.

I was able to access it few days ago without any issues.

if you can access in past it could be Certificate issue and maybe certificate expired.

pls check certificate

Check the disk usage with df -h via SSH and try to start the services manually.

Start all services: service-control --start --all

You can check the logs of the services that won't start to have an indication. Location : /storage/log/VMware/"service"/"service.log"

check if the certificates are still valid:

vCenter Appliance: Run the following command in a console window or SSH session to the vCenter VM:

for store in $(/usr/lib/vmware-vmafd/bin/vecs-cli store list | grep -v TRUSTED_ROOT_CRLS); do echo "[*] Store :" $store; /usr/lib/vmware-vmafd/bin/vecs-cli entry list --store $store --text | grep -ie "Alias" -ie "Not After";done;

I am trying to open the Vcenter VM but it is showing DCUI aborted by exception.

I am trying to access it using putty but it is saying connection refured.

"DCUI aborted by exception" . that sounds the the Photos OS vCSA has root partition full.

Reboot vCSA VM and check once. "/" cleanup might be needed.

Hi @Ajay1988 ,

Thank you for that. Would it be ok to force restart the VM? As I can't connect via ssh and can't even open the browser.

Yes..Force restart the vCSA VM from ESXi.

If you are able to access VAMI:5480 so check which service has been started and which one is not.
you will be able to check all partitions.

Hi @Ajay1988 ,

Thanks for your help. After I forced restart the VM, it works as normal after that. It just took a long for it to run all the services and able to access on a browser.
