503 Service Unavailable (Failed to connect to endpoint)

September 13, 2022

Hi Friends,

IT was mainly two type of issues

1. Services not Started
2. Certificate issue

Steps we need to perform to resolve this:-

Checked the certs SSL and STS were valid
Restarted the services. Service was stuck in vapi-endpoint

Services-control --start --all and services-control --stop --all

Checked vapi/endpoint logs shows No subject alternative name matching IP address.

log files location :- C:\ProgramData\vCenterServer\logs\vapi\endpoint.log

As PNID was IP address we need to update IP address.
PNID = the system name (FQDN or IP address) is used as the PNID.
Followed the KB https://kb.vmware.com/s/article/2112283?lang=en_us
Re-generated the SSL certs updated the IPaddress and hostname to IP address (Hostname always should be PNID)
Command to check PNID is mentioned in the KB.

Windows: "C:\Program Files\VMware\vCenter Server\vmafdd\vmafd-cli.exe" get-pnid --server-name localhost
https://kb.vmware.com/s/article/2130599

Once certs were re-generated all the services were up and running.
We were able to access vCenter.
